Binance founder Changpeng Zhao (CZ) has reignited discussion within the Bitcoin community after suggesting that dormant Bitcoin holdings, including wallets believed to belong to Bitcoin creator Satoshi Nakamoto, could eventually be frozen if they remain vulnerable to quantum computing attacks. Speaking on the Galaxy Brains podcast with Galaxy Research head Alex Thorn, CZ presented the idea as a question for the broader Bitcoin community rather than a proposal he personally intends to implement. He later clarified that reports claiming he wanted to freeze Satoshi’s Bitcoin for a year misrepresented his comments. The debate follows growing concerns about quantum computing and its potential impact on Bitcoin security. Earlier this year, Google Quantum AI released research indicating that future quantum computers may be able to break the cryptographic systems protecting digital signatures with fewer than 500,000 qubits, significantly reducing previous estimates. Security experts warn that Bitcoin addresses with exposed public keys could become targets for quantum attacks. If a sufficiently powerful quantum computer emerges, attackers could theoretically derive private keys and gain access to funds stored in vulnerable wallets. Transitioning Bitcoin to quantum-resistant cryptography is considered the long-term solution, but implementing such changes across the network could take years. According to estimates, more than one-third of Bitcoin’s supply has already revealed public keys on-chain. This includes the roughly 1.1 million BTC believed to have been mined by Satoshi Nakamoto between 2009 and 2010. At current market prices, those holdings are valued at approximately $70 billion. CZ’s comments align with ideas proposed in BIP-361, a draft proposal that would gradually restrict transactions from quantum-vulnerable addresses before ultimately invalidating legacy signatures. Supporters argue that locking vulnerable coins may prevent theft, while critics view any forced restriction as a violation of Bitcoin’s principle that ownership cannot be altered without a private key. The issue remains

The photonics-first contrarian of the public quantum sector, building room-temperature optical machines and the chips behind them. This is its commercial history and how the QUBT business works. QCi, formally Quantum Computing Inc (Nasdaq: QUBT), is the photonics-first contrarian of the public quantum sector. Rather than chase superconducting or trapped-ion qubits, it builds room-temperature optical machines and the photonic chips behind them, and it owns a foundry to make them. This is the commercial history of QCi, from an obscure shell company to a Nasdaq name with its own thin-film lithium niobate fabrication plant. What the company does Quantum Computing Inc, known as QCi, designs photonic quantum machines and the integrated optical chips that power them. Its systems use light moving through engineered chips rather than supercooled superconducting circuits, which the company argues allows room-temperature operation and lower energy use. The product line spans optimisation machines, photonic sensors and quantum networking hardware. QCi also sells foundry services, making thin-film lithium niobate photonic chips for itself and for outside customers. That dual role, product company and chip manufacturer, is unusual in the sector. It lets QCi pitch both finished machines and the building blocks that other photonics developers need. The company frames its approach as practical and affordable, arguing that photonic machines can run in ordinary server rooms without the heavy cryogenics that superconducting and trapped-ion systems require. That positioning is central to its sales pitch, which targets buyers who want quantum and advanced-optics capability without building specialised facilities. Whether the performance matches that promise is the question its critics keep asking.

Singaporean brothers use unsolvable maths equations to build modern, unbreakable encryption Sign up now: Get ST's newsletters delivered to your inbox SINGAPORE – Lim Meng Liang, 38, spends most of his time solving the impossible. As a specialist in Diophantine equations – notoriously complex mathematical problems famous for having no solutions – Lim operates in a field most regarded as academic and esoteric. But when he secured his first US patent in 2022 for novel methods to exploit these unsolvable equations to encrypt data, he created a cryptographic wall that is practically unbreakable for hackers. “I could have just framed the patent and kept it on the wall,” said the National University of Singapore (NUS) applied mathematics alumnus, who runs his own investment firm. “But after some hard thinking and discussions with my brother, we decided to do something with it.” In 2023, Lim joined forces with his older brother Ken Lin – who quit his 15-year finance career – to found Aires Applied Quantum Technology. The brothers have different surnames due to an error made by their parents when registering Lin’s birth certificate. The start-up, which has secured more than US$2 million (S$2.6 million) from private investors and local agencies such as Enterprise Singapore, is now actively looking to list in markets such as the US, Singapore or Japan to raise “an eight-digit figure” to market its product globally. Its flagship product developed over the last three years, LionGuard, is a mobile app that encrypts files stored on devices or in the cloud or networks. With a monthly subscription of $388 per user, it is designed to be a fuss-free tool to protect enterprises and users from cyberthreats enabled by quantum computers.

Scientists Achieve First Entanglement of Three Remote Atomic Qubits in Quantum Network Duke University and IonQ create first three-node quantum network. Researchers from Duke University and IonQ have announced the creation of the first fully distributed three-node quantum network based on individual atomic qubits, according to Quantum Computing Report. The team successfully formed a tripartite entangled state, known as the Greenberger–Horne–Zeilinger state, among three remote quantum nodes connected by photonic channels. What Happened Quantum entanglement allows multiple particles to remain connected regardless of the distance between them. A change in the state of one particle instantly affects the state of others, making this effect a cornerstone for future quantum networks and the quantum internet. Previously, scientists demonstrated entanglement between two remote quantum nodes and even three-node networks on other physical platforms. However, this is the first time such a result has been achieved with individual atomic qubits, which can be independently controlled, read, and scaled for building computational systems. Why It Matters The main challenge of quantum computers is scalability. Building a large quantum processor is extremely difficult due to errors and hardware limitations. As a result, many developers are focusing on a modular architecture: instead of one giant computer, a network of many quantum nodes connected by photons is created. This approach is reminiscent of the development of the classical internet, where computing resources are distributed among many servers. The new experiment is a step in this direction. Researchers demonstrated that individual atomic memories could form a shared quantum state through photonic connections while maintaining high accuracy in quantum operations. During the experiment, the scientists achieved a fidelity of the entangled state at 84–88% and for the first time closed the so-called “detection loophole” for a fully distributed multipartite quantum state. Additionally, the results confirmed the violation of Mermin’s

| Professor Nguyễn Thị Thanh Mai, chancellor of VNU-HCM, speaks at the national scientific conference on quantum technology in HCM City on June 19. — Photos courtesy of VNU-HCM | HCM CITY — Việt Nam must urgently build an autonomous national quantum capability to protect its digital sovereignty against future decryption threats, experts said at a major national scientific conference in HCM City on June 19. The conference called "Quantum technology in the new era: International trends, opportunities, and requirements for Việt Nam", was co-hosted by Vietnam National University-HCM City (VNU-HCM) and the Vietnam Academy of Science and Technology (VAST). It brought together top policymakers, scientists, and representatives from the ministries of public security and national defence to chart a strategic roadmap for the country. Speaking at the conference, Professor Nguyễn Thị Thanh Mai, chancellor of VNU-HCM, said quantum technology has rapidly evolved from academic theory into a critical national security asset. "The question is no longer whether quantum technology should be a priority, but how Việt Nam can develop the speed, foundation, and autonomy to master this field, reduce external dependencies, and integrate deeply into the global value chain," she said. Delegates warned of a pressing non-traditional security risk known as the "harvest now, decrypt later" strategy, where malicious actors intercept and store encrypted data today to decrypt it once quantum computers become sufficiently powerful. Because of this, experts urged that developing post-quantum cryptography and protecting national digital infrastructure must begin immediately. To eliminate fragmented investments and maximise resources, the conference introduced a proposed "Hub-and-Nodes" strategic network architecture for the 2026-45 period. Under this framework, a single national centre will act as the coordinating ‘hub’ to manage and distribute resources to five specialised ‘nodes’: the Ministry of Public Security, the Ministry of National Defence, VNU-Hà Nội, VNU-HCM, and VAST.

Changpeng Zhao Proposes Freezing Satoshi’s Bitcoin to Counter Quantum Computing Threat Share: Binance founder Changpeng Zhao proposed freezing or removing the roughly one million Bitcoin (≈5% of supply) attributed to Satoshi Nakamoto after a quantum-resistant crypto upgrade, with a suggested 6–12 month grace period for any legitimate owner to move funds. He described quantum computing as a manageable but long-term threat (most experts estimate 10–15 years) and emphasized that any protocol change must follow broad community consensus to preserve crypto security. The idea is highly contentious for governance and decentralization and would create a permanent supply shock with major market implications, so debate over adoption, protocol upgrades and market risk will intensify. BitcoinWorld Changpeng Zhao Proposes Freezing Satoshi’s Bitcoin to Counter Quantum Computing Threat Binance founder Changpeng Zhao has ignited a fresh debate within the cryptocurrency community by proposing that the roughly one million Bitcoin believed to be controlled by Satoshi Nakamoto should be frozen or removed from circulation after a quantum-resistant network upgrade. In a recent podcast interview, Zhao addressed growing concerns about quantum computing’s potential to break Bitcoin’s cryptographic security, arguing that while the threat is not immediate, proactive measures are necessary to prevent an unfair seizure of the dormant coins. Quantum Computing: A Manageable Risk, Not a Fatal Blow Zhao emphasized that quantum computing does not pose an existential threat to Bitcoin itself. The network can be upgraded with quantum-resistant cryptographic algorithms, a process that would require broad community consensus. He described the risk as manageable, provided the industry acts before quantum computers become powerful enough to crack existing encryption standards. The timeline for such a threat remains uncertain, with most experts estimating it is at least a decade away, but Zhao argued that planning should begin now.

The technique offers an unexpected new level of control over components that could power future quantum computers, communications systems, and sensors. - Share: Researchers at the University of Technology Sydney have demonstrated a new way to control tiny sources of quantum light by twisting atomically thin layers of hexagonal boron nitride. The advance provides scientists with a new method for tuning quantum emitters, which are microscopic light sources that could play an important role in future technologies such as quantum computing, secure communications, and ultra-sensitive sensors. Lead author Dr. Angus Gale said the work offers researchers a valuable new tool for making these quantum systems more practical. "You can measure these quantum emitters and see that they exist, but it's hard to make them work in practice. This gives us a lever to get closer to that -- a step towards the realization of quantum technologies," said Dr. Gale. Twisting Layers Changes Quantum Light During the experiments, Gale and his team found that twisting the material could significantly alter both the color and wavelength of the light emitted by the quantum emitters. The magnitude of the change was especially noteworthy. Most studies create a device at a specific twist angle and leave it unchanged. In contrast, the researchers were able to repeatedly lift, rotate, and restack the material, allowing them to continuously modify its properties. "We're leveraging the fact that this material,

The threat posed by post-quantum technology is no longer theoretical; it is already shaping the risk landscape today. While quantum computing promises groundbreaking advances, it will simultaneously undermine the cryptographic foundations that protect our digital economy. What has changed is the timeline. The question is no longer whether quantum computers will crack current encryption, but when. Attackers are already exploiting this vulnerability. “Harvest now, decrypt later” has become the biggest concern for businesses, with 61 percent of IT security professionals surveyed in Thales’ Data Threat Report citing it as their greatest quantum risk. Sensitive data stolen today might not be exposed for years, creating a long-term security risk that many companies still underestimate. At the same time, most companies are unable to react effectively. Only 34 percent of those surveyed in the report have complete transparency about where their data is located. Less than half of sensitive cloud data is encrypted. You can't protect what you can't see – and in the quantum context, this transparency gap becomes a strategic, not just an operational, risk. Post-Quantum Cryptography There are now signs of progress. Nearly six out of ten companies are already experimenting with post-quantum cryptography, signaling a shift from awareness to action. But experimentation alone is not enough. The real challenge lies in scaling this transition: embedding crypto agility, modernizing key management, and determining where cryptography stands in increasingly complex, cloud-first environments. Preparing for a post-quantum world is not a one-time upgrade; it's a transformation of how organizations approach data security. This means acting now: identifying cryptographic dependencies, prioritizing high-value data with long confidentiality cycles, and laying the foundations for quantum-safe architectures.

D-Wave's Quantum Spring Meets a Scientific Chill: Can Commercial Momentum Outrun a Credibility Gap? 20.06.26 14:42 Börse Global (en) D-Wave Quantum is riding a wave of real-world contracts that would have seemed far-fetched a year ago — yet a fresh academic study has reopened the debate about whether its hardware actually delivers the promised quantum advantage. The tension between commercial traction and scientific scrutiny now defines the stock's trajectory. The company's first-quarter bookings hit $33.4 million, anchored by a $20 million system sale to Florida Atlantic University and a $10 million service agreement with a Fortune-100 corporation. Those are not experimental grants; they are capital budgets being allocated to quantum optimization. At the Qubits Europe 2026 conference in London, D-Wave presented itself as a business with a pipeline, not just a lab. That narrative has helped the share price climb 28% over the past 30 days, closing Friday at €21.24 — a marginal 1.48% dip that barely dented the rally. Yet the same week that D-Wave touted its commercial wins, a team at the Flatiron Institute published findings in Science that chip away at the foundation of the company's 2025 quantum-advantage claim. Using a classical belief-propagation algorithm, the researchers simulated a complex magnetic system that D-Wave had previously held up as proof its annealers outperformed classical computers. The result does not accuse D-Wave of dishonesty, but it illuminates the sector's chronic problem: classical algorithms keep catching up. The benchmark for genuine quantum supremacy is a moving target, and investors are left guessing when it will stop moving. Technically, the stock is sitting on a knife-edge. It closed just above the 200-day moving average of €20.98 — a level that often separates a recovery from a relapse. Having nearly doubled from its 52-week low of €11.12 set in late March, the

CZ proposes freezing Satoshi Bitcoin stash to stop quantum theft Binance founder Changpeng Zhao has proposed freezing up to 1 million Bitcoin linked to Satoshi Nakamoto if those coins remain unmoved after a future transition to quantum-resistant cryptography. - CZ proposed freezing inactive Bitcoin addresses after a future migration to quantum-resistant cryptography. - His plan could affect up to 1 million BTC believed to be linked to Satoshi Nakamoto. - Bitcoin developers remain divided between protecting vulnerable coins and preserving property rights. Speaking during a June 18 appearance on the Galaxy Brains podcast hosted by Galaxy Research President Alex Thorn, Zhao said quantum computing does not pose an insurmountable threat to Bitcoin because quantum-resistant cryptographic systems already exist. Zhao argued that the more difficult task would be coordinating a network-wide migration to those technologies if quantum computers eventually become capable of breaking Bitcoin’s current security model. Speaking about Bitcoin addresses that have remained inactive for years, including those widely believed to belong to Satoshi Nakamoto, Zhao said the network should establish a migration period of roughly six to twelve months after any future upgrade to quantum-resistant cryptography. Under his proposal, holders would be given time to move their coins to protected addresses before legacy addresses are retired. If no movement occurs during that period, Zhao suggested the remaining Bitcoin should be frozen under the new protocol. He argued that allowing vulnerable addresses to remain active indefinitely could eventually result in quantum-capable attackers gaining access to coins whose owners are no longer participating in the network. According to Zhao, such an outcome would create an unfair method of redistributing Bitcoin because ownership would effectively transfer to whoever first develops the ability to crack those addresses. He emphasized that the decision should not be his to make and said any change would

The conference was jointly organized by Vietnam National University-Ho Chi Minh City and the Vietnam Academy of Science and Technology. Speaking at the event, Prof. Dr. Tran Hong Thai, head of the academy, said that quantum technology emerges as one of the most strategic emerging fields, with the potential to fundamentally transform computing, communications, sensing, materials science, information security, defense, and other high-tech industries. He noted that second-generation quantum technology is moving beyond laboratory research and is increasingly centered on three major pillars, including quantum computing, quantum communications, and quantum sensing. The technology is becoming directly linked to competitiveness, technological sovereignty, data security, and national position in the digital era. “Quantum technology is an extremely challenging field, but it is not beyond Vietnam’s reach,” he stressed. “It is true that Vietnam is behind the leading powers, but being behind does not mean we cannot participate, nor does it mean we should remain on the sidelines.” The door remains open for countries that are able to identify suitable development directions, focus on their resources effectively, organize their scientific workforce strategically, and consistently build capabilities over the long term, prof. Thai said. He affirmed that Vietnam should pay close attention to quantum technology. As quantum computers become powerful enough to perform advanced calculations, many of the encryption systems currently protecting financial information, citizen data, digital transactions, and critical national infrastructure could face significant security risks, he explained. Quantum technology also carries strategic importance for national defense, security, digital economy, and national competitiveness.

Amaravati hits major milestone in quantum computing, dilution refrigerator reaches 4 Kelvin Andhra Pradesh's quantum computing facility in Amaravati has achieved a major milestone with its indigenous dilution refrigerator as it reached 4 Kelvin (minus 269 degrees Celcius). Here is what this means for the future of quantum computing in India. Technology is progressing fast. Today, we hear discussions about how AI and AI agents are changing the way the world works. But there is another technology that is gaining traction globally, quantum computing. With Andhra Pradesh’s Amaravati Quantum Valley (AQV) aiming to lead this field. And now, Amaravati has reached a major milestone with its indigenous dilution refrigerator reaching 4 Kelvin, or minus 269 degrees Celsius. The indigenous dilution refrigerator was created at the Quantum Reference Facility in Medha Towers, Amaravati. The Andhra Pradesh government said this was the first major technical milestone for the state’s quantum hardware facility. According to reports, the system was built with more than 80 per cent domestically-sourced components, making it one of the coldest temperatures achieved in a research facility in India with such a high level of local materials. What is quantum computing? Before we delve into why this matters, we need to understand quantum computing. You see, quantum computing is more complex than regular computers. Unlike regular computers that store information in bits – 0 or 1 – quantum computers use qubits. In simple terms, qubits allow us to find out different probabilities and answers all at once, instead of going through each problem individually. This, in theory, can allow us to do research or solve problems that could've taken hundreds of years in days. But qubits are far more fragile, and need precise conditions to function. They must be cooled to near absolute zero – around 15 millikelvin, colder than

Cloud-based optimization developer Fixstars Amplify Corporation has added IonQ’s trapped-ion quantum computing environment as a standard execution backend within its optimization platform. The integration enables enterprise users in the United States and Japan to develop, test, and execute combinatorial optimization workloads across hardware-agnostic pipelines. Under the initial deployment framework, access to IonQ’s cloud-based quantum simulator is available to existing platform account holders at no additional charge, while access to actual trapped-ion hardware processing units is scheduled to roll out progressively through tiered, paid subscription plans. Unified SDK Architecture and Hybrid Optimization Loops The backend integration is orchestrated by combining the Fixstars Amplify SDK—a unified software development library designed to formulate combinatorial optimization problems—with Amplify Quantum, a specialized extension package that automates the translation of mathematical models into executable quantum structures. When an engineer calls the platform’s core execution functions, the extension dynamically converts the optimization model into parametric quantum circuits, handles the API communication downlinks, and manages the iterative feedback loop between classical and quantum layers. This unified interface allows users to switch their backend solver clients from classical GPU engines to trapped-ion targets by changing the destination client class configuration within their local Python environments. The software stack supports several hybrid variational optimization algorithms optimized for Noisy Intermediate-Scale Quantum (NISQ) systems: - Quantum Approximate Optimization Algorithm (QAOA): Executes parameter-driven state transformations to solve unconstrained Ising polynomials of arbitrary degrees. - Constrained QAOA: Integrates structural N-HOT constraint boundaries directly into the circuit generation layer to prevent the sampling of invalid states. - Recursive QAOA: Systematically reduces the effective size of the mathematical problem graph by recursively fixing highly correlated variable pairs through classical pre-processing loops. Hardware Topology and All-to-All Qubit Interaction Integrating IonQ’s platform into the Fixstars portfolio expands the compiler’s range beyond traditional superconducting architectures and classical annealing simulators.

A single transistor that behaves like a brain cell in the deep freeze could help unlock the next generation of quantum computers and space exploration systems. Researchers at the University of Hong Kong (HKU) have developed a new type of brain-inspired electronic hardware that can operate at temperatures close to absolute zero. The breakthrough could help address one of the biggest challenges facing quantum computing while also opening new possibilities for future deep-space missions. The work was carried out by scientists from HKU’s Department of Electrical and Computer Engineering within the Faculty of Engineering and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC). Their newly developed programmable neuromorphic platform functions in extremely cold environments and could provide a practical way to improve the scalability of quantum computers. Brain-Inspired Computing at Near Absolute Zero The research team, led by Professor Yuhao Zhang and PhD student Xin Yang, found a new method for creating and controlling negative differential resistance (NDR) in industry-standard Silicon Carbide (SiC) MOSFETs. Using this approach, they demonstrated for the first time that a single transistor can reproduce the energy-efficient “spiking” activity seen in biological neurons at temperatures as low as 10 mK. This achievement is significant because quantum computers operate under extremely cold conditions. Their qubits are highly sensitive and must be maintained at millikelvin temperatures. However, the electronic systems used to control those qubits typically consume substantial power and generate heat. As a result, today’s silicon-based controllers must be positioned farther away from the qubits, creating a complex web of wiring that limits system performance and makes it more difficult to build larger quantum computers. “Our work introduces a hardware platform that can be integrated alongside quantum processors,” said Professor Zhang. “By using the unique carrier dynamics in silicon carbide, we can create circuits that are

South Korean launch services company INNOSPACE has signed a memorandum of understanding (MOU) with quantum software developer Norma to co-engineer space-based quantum computing technologies. The strategic agreement sets up a collaborative framework across three operational areas: the execution of in-orbit technical demonstrations, joint participation in state-funded aerospace R&D programs, and the conceptual planning of a dedicated Space Quantum Computing Center. The project addresses the growing data bottlenecks in orbital networks, where the increasing complexity of satellite mega-constellations demands decentralized, high-performance computing to handle localized telemetry and payload data processing. The initial technical milestone of the partnership centers on integrating a compact quantum computing payload, built around a dedicated Quantum Processing Unit (QPU), into INNOSPACE’s HANBIT launch vehicle. Operating the hardware directly from the rocket platform during flight allows the engineering teams to verify the mechanical stability and functional operability of QPU components when subjected to the structural vibrations, radiation levels, and thermal fluctuations of an active aerospace environment. The upcoming flight profiles will serve as a physical validation gate to assess how quantum coherence and qubit gate stabilities hold up outside traditional terrestrial laboratory baselines. The data gathered from the HANBIT demonstration flights will establish the engineering parameters for the proposed Space Quantum Computing Center. Envisioned as a hybrid, cloud-linked orbital data infrastructure network, the facility will deploy specialized quantum algorithms to manage large-scale satellite fleet trajectories, optimize real-time orbital resource allocations, and secure communication downlinks using quantum-resistant cryptographic keys. This infrastructure layer builds upon Norma’s existing Q Platform—a hardware-agnostic cloud ecosystem that integrates multi-QPU backends with corporate networks through established partnerships with domestic tech providers like KT Cloud and Kakao Enterprise.

By mimicking how the brain operates, neuromorphic computing can use dramatically less energy than conventional electronic AI chips. However, even the most sophisticated neuromorphic devices today are still quite simple, using only a small fraction of the number of connections found in human neurons. Now, a new study suggests that by using sound waves, neuromorphic devices can better mimic biological neurons and operate faster and with greater energy efficiency than their electronic counterparts. “This could make future neuromorphic hardware more compact, more parallel, and more efficient for tasks that require combining many features, such as pattern recognition, sensory processing, and data analysis,” says Xiaodong Yan, an assistant professor of materials science and engineering and electrical and computer engineering at the University of Arizona in Tucson. Just as brains use synapses—the links connecting neurons—to help them both compute and store data, neuromorphic devices often combine both operations. Doing so can reduce the energy and time needed for conventional microchips to shuttle data between processors and memory. Each human neuron may have thousands of synapses connecting them with other cells; one kind of neuron found in the cerebellum, the Purkinje cell, may have as many as 100,000 synapses. This extraordinary level of connectivity lets each human neuron “combine different pieces of information, compare them, and respond depending on the context,” Yan says. In contrast, most conventional neuromorphic devices are essentially “one artificial synapse,” Yan says. Building an artificial neuron with as many synapses as a human neuron would require wiring many separate devices together. “This increases wiring, energy cost, and hardware complexity,” Yan says. Using Quantum-Like Tricks Enables Parallel Computing Recently, scientists have developed acoustic devices in which sound waves can encode multiple values in its waves phase. These phase bits, or phi-bits, can in turn support quantum-like logic gates and parallel

New twisting technique gives scientists unprecedented control of quantum light Researchers use twisted hBN layers to significantly tune quantum light sources for future quantum devices. Scientists have discovered a new way to control quantum light sources by twisting atomically thin layers of a material known as hexagonal boron nitride (hBN), a breakthrough that could help bring quantum technologies closer to practical use. Researchers from the University of Technology Sydney found that rotating and restacking layers of hBN can significantly alter the color and wavelength of light emitted by quantum emitters embedded within the material. Quantum emitters are tiny light sources that can produce single photons, making them important building blocks for future quantum computers, secure communication networks, and highly sensitive sensors. While scientists have been able to detect and study these emitters, controlling them has remained a major challenge. The team says its approach offers a new way to tune these light sources by exploiting the unique layered structure of hBN, a material that can be repeatedly separated, twisted, and reassembled. Twisting light into control Lead author Dr. Angus Gale said the findings provide researchers with a new tool for manipulating quantum emitters. “You can measure these quantum emitters and see that they exist, but it’s hard to make them work in practice. This gives us a lever to get closer to that – a step towards the realisation of quantum technologies,” said Dr Gale. In experiments, the researchers were able to produce a significant shift in the emitted light by changing the twist angle between layers. Unlike many studies where materials are assembled once and left unchanged, the team repeatedly picked up, twisted, and restacked the layers while continuing to modify the optical properties. “We’re leveraging the fact that this material, hexagonal boron nitride (hBN), is layered. We can
