Quantum IPO Pipeline Reopens: 1 Pure Play and 2 Enablers Stand Out The quantum computing space is beginning to show early signs of a capital markets inflection, as fresh funding rounds and a gradually reopening IPO pipeline point to improving investor appetite for deep-tech plays. A notable recent development was Finland-based IQM Quantum Computers raising €50 million (about $57 million) from funds managed by BlackRock in March 2026 ahead of a planned public listing in the United States and Helsinki, according to Reuters. The funding is expected to support chip development and international expansion, while also positioning the company for public market entry. This transaction indicates a broader trend of rising institutional participation in quantum computing. BlackRock’s involvement follows earlier large-scale funding activity across the sector, including capital raises by companies such as PsiQuantum, which has reportedly pursued funding rounds in the $750 million–$1 billion range (Reuters). Meanwhile, in addition to IQM’s plans, Quantinuum, a unit formed by HoneywellHON, has also indicated intentions to go public, signaling a potential reopening of equity markets for advanced computing firms. Government Backing Strengthens Long-Term Growth Outlook The growing presence of institutional investors suggests increasing confidence that quantum computing, while still pre-commercial at scale, is evolving into a long-duration strategic investment theme alongside artificial intelligence. Importantly, this private and public market activity is supported by strong government backing. The European Union and national governments have committed billions toward quantum research and commercialization through initiatives such as the European Innovation Council and broader regional programs, helping companies like IQM scale their technology base. Investment Strategy: Balancing Pure Plays With Infrastructure Enablers Under current market conditions, allocating capital to quantum computing appears increasingly rational for investors with a long-term horizon. While the sector remains early-stage and inherently volatile, the combination of rising institutional funding, government support

Here’s what you’ll learn when you read this story: - A physicist challenges the core idea of quantum mechanics, that events are truly random. He says a hidden framework of rules may influence outcomes. - That’s because our current math makes quantum outcomes only appear random, while the reality of nature may have an underlying order we can’t track. - This limitation means the evolution of quantum computers may hit a fundamental limit, which could be proof for his theory, he believes. Since the birth of quantum mechanics—the early 20th century theory that governs the strange behavior of particles at the smallest scales—the notion of randomness has taken on an almost mythical status in physics. In the microscopic world of electrons flickering around atoms and light waves hitting a photon detector, outcomes are random, according to the laws of probability. However, some scientists theorize that quantum mechanics is incomplete—because it’s missing the underlying truth that events aren’t totally random after all. Over time, that idea has seeped beyond physics itself, shaping a broader intuition: that a deep-seated fundamental structure determines the outcome of even seemingly random events. And if such uncertainty lies at the core of reality, then it would imply that these rules not only influence physical phenomena, but could also influence the random events in your life—good and bad. Timothy Palmer, PhD, a Royal Society research professor in climate physics at the University of Oxford, points to what he thinks is the fundamental problem: not reality itself, but the mathematics used to describe it. In a companion paper currently under review in Proceedings of the Royal Society, he says something simple but radical: that not every mathematically possible state allowed by quantum theory actually exists in the real world. Take a look at the math itself. The theory

Lloyds Banking Group has carried out an experiment into how quantum computing could help to identify money mules, it announced Tuesday. The bank said the experiment “marks a major step” in building the skills and technology needed to tackle economic crime in the future. Conducted in partnership with IBM, the experiment tested multiple quantum algorithms to see whether patterns of known money mule behaviours could be identified within a larger transactional graph. It is the first known application of a quantum optimisation algorithm to detect money mule accounts using anonymised real-world transaction data on actual quantum hardware, according to the bank. The experiment successfully identified a real money mule that had been deliberately embedded in the data to validate the approach, which Lloyds said demonstrated how real-world financial crime challenges could be tackled in the future using algorithms running on quantum computers. The bank said money mule networks – where criminal behaviour is hidden within vast webs of legitimate transactions – are a significant enabler of scams and fraud. It added that insights from this experiment could one day help banks detect sophisticated fraud earlier, better protecting their customers. Lloyds created a working group of quantum ambassadors – including specialists in physics, maths and computer science from across the business – to manage the experiment. Over the nine-month project, this team worked alongside Lloyds’ economic crime prevention experts and IBM’s specialists to explore how quantum computing could be used to uncover complex fraud patterns that can be challenging for traditional computers to detect. “Financial crime is becoming more complex and more network driven, which means we need to keep pushing the boundaries of technology to protect customers,” said Ron van Kemenade, chief operating officer at Lloyds Banking Group. “While quantum computing is still emerging, this experiment has allowed us to

Cloudflare aims to make its entire platform fully post-quantum secure by 2029 at the latest, including authentication systems. The revised timeline follows new developments in quantum computing that suggest existing cryptographic standards may be cracked sooner than expected. The reason is concrete. Research by Google and Oratomic shows that algorithms and hardware can break widely used encryption methods, including RSA-2048 and elliptic curve cryptography. Cloudflare views this as evidence that the arrival of “Q-day”—the moment when quantum computers can break current encryption—is drawing nearer. Some projections place that moment as early as the end of this decade. Cloudflare points to progress on three parallel fronts: quantum hardware, error correction, and quantum algorithms. Improvements in areas such as neutral-atom architectures and more efficient error correction reduce the resources required to break encryption. Advances in algorithms simultaneously lower computational complexity. According to the company, the combination of these three factors makes the threat landscape more dangerous sooner than previously thought. Authentication as a New Priority For a long time, the focus was on protecting encrypted data against “harvest now, decrypt later” attacks. But now that the timeline is shortening, the risk is shifting to authentication. Quantum attackers could then forge login credentials and gain direct access to systems. That makes the problem even more concrete. Migrating to post-quantum authentication is more complex than rolling out post-quantum encryption, due to dependencies on long-lived keys, third-party systems, and certificate infrastructure. Cloudflare also emphasizes that legacy cryptographic systems must be completely disabled to prevent downgrade attacks. The company has already rolled out post-quantum encryption across a large portion of its network. More than half of the human traffic that Cloudflare processes now uses post-quantum key agreement. Post-quantum authentication support will follow in 2026, with a broader rollout across the platform in 2028. By 2029, all

IQM Quantum Computers has entered into a commercial agreement with Galaxy Systemy Informatyczne for the on-premises delivery of an IQM Radiance 54-qubit system. Scheduled for installation at Galaxy’s data center in Zielona Góra, Poland, in the fourth quarter of 2026, the superconducting quantum computer will be integrated with the firm’s existing High-Performance Computing (HPC) infrastructure. This transaction represents an instance of direct hardware procurement by a private IT service provider, following IQM’s previous deployments at public research hubs such as LRZ in Germany and CINECA in Italy. The acquisition is intended to provide Galaxy with a dedicated hardware environment to support internal R&D and secure data processing. By maintaining the 54-qubit system on-site, the company aims to reduce its reliance on external cloud-based quantum services and manage the security of sensitive workloads in-house. Galaxy has identified several target application areas for the system, including space technologies, financial market modeling, and energy grid optimization. The integration of quantum resources into their existing HPC stack is designed to facilitate the development of hybrid algorithms for these industrial sectors. This deployment follows IQM’s established roadmap for its Radiance line, which utilizes a superconducting transmon architecture with tunable couplers. To date, IQM has sold 21 quantum systems to 13 customers globally, primarily within the academic and national laboratory sectors. The Zielo Góra installation will add to Poland’s technical infrastructure, leveraging the region’s existing expertise in mathematics and physics.

Grayscale head of research Zach Pandl argues that Bitcoin’s biggest obstacle to surviving the quantum computing era isn’t finding a technical solution — it’s getting the community to agree on one. Pandl noted that Bitcoin actually carries lower quantum risk than most other cryptocurrencies, thanks to its UTXO model, proof-of-work consensus, and the fact that certain address types aren’t quantum vulnerable at all. Three options, one hard choice The central debate revolves around roughly 1.7 million BTC sitting in early P2PK addresses — including Satoshi’s estimated 1 million BTC stash, worth around $68 billion — where private keys are lost or inaccessible. Pandl laid out three paths the community could take: burn the coins, deliberately slow their release by rate-limiting spending from vulnerable addresses, or do nothing. He wrote: “All are conceptually doable, but the challenge is reaching a decision, and the Bitcoin community has a history of contentious debates over protocol changes, including last year’s dispute around image data stored in blocks.” Mow warns against rushing the fix Samson Mow, Bitcoin advocate and Jan3 founder, pushed back against calls from Coinbase executives to accelerate the move to post-quantum cryptography, arguing that speed could create more problems than it solves. His concern is that a rushed transition could expose Bitcoin to present-day threats before it ever neutralizes future ones. He stated: “Simply put: make Bitcoin safe against quantum computers just to get pwned by normal computers.” Mow also flagged a concrete technical cost: post-quantum signatures could be 10–125x larger than current ones, massively reducing network throughput and potentially reigniting a debate reminiscent of Bitcoin’s block size wars of 2015–2017. Work should continue, just not rushed Despite opposing a rushed transition, Mow was clear that preparation shouldn’t stop entirely. He said: “Given that quantum computers don’t actually exist and likely won’t

Abstract Variational quantum algorithms (VQAs) are constrained by a trade-off: deeper circuits can cover a larger reachable quantum states but suffer from barren plateaus, while shallow circuits remain trainable yet can have insufficient reachability to the target state. Here, we propose a general framework to address this challenge by enhancing the VQA performance with a designed input state constructed using a linear combination technique. This approach modifies the set of states reachable by the original circuit, enhancing accuracy while preserving efficiency. We provide a rigorous proof that such framework increases the performance of any given VQA ansatz, and demonstrate its broad applicability across different ansatz families. In ground state preparation for representative quantum many-body models, it achieves consistently higher accuracy than standard methods at the same gate budget. These results highlight input-state design as a powerful complement to circuit design for improving reachability of the target state within a fixed ansatz.

Quantum computers are often described as the supercharged engines of the future — machines capable of solving certain problems that are classically intractable for today’s most powerful computers. But there’s a catch: even the most advanced quantum computers cannot yet easily communicate with one another over long distances. “It’s like building a network of high-capacity power plants without the transmission lines needed to connect them into a grid,” said Yanan (Laura) Wang, assistant professor of electrical and computer engineering at the University of Nebraska–Lincoln, who is working to build that missing piece with support from one of the U.S. Department of Energy’s most competitive grant programs. Wang received a five-year, $876,663 Early Career Research Program award, which runs through August 2030. The objective is to solve one of the most challenging engineering problems in quantum technology. Today’s quantum computers, developed by industry leaders like IBM and Google, operate using microwave frequency signals, while quantum communication systems — needed to link those computers together — use light at frequencies hundreds of thousands of times higher. “The computation unit and the communication unit have this huge frequency mismatch,” Wang said. “That’s why it requires a bridge to transfer the information between those two.” Without that connection, a true quantum network — the equivalent of the internet for quantum machines — remains out of reach. Wang’s solution centers on quantum grade mechanical resonators and waveguides, devices capable of interacting with both microwave and optical signals. Her team will build these devices using van der Waals-layered crystals, a family of materials that includes graphene and other atomically thin semiconductors. These materials can be peeled down to a single atomic layer while retaining exceptional strength, making them ideal for high performance mechanical devices. “They are just atomically thin … but the in-plane covalent bonds are

A Sydney researcher’s “blueprint” for quantum computing error correction developed while on an industry placement at IBM has been adopted by the global tech giant. In a paper published last week in Nature Physics, University of Sydney School of Physics’s Dr Dominic Williamson and IBM researcher Theodore Yoder outlined a new approach to quantum error correction that may speed up the journey to developing reliable quantum computers. Williamson completed this research while on a sabbatical working with IBM’s Quantum Information Theory and Error Correction group in California. The new approach has now been integrated into IBM’s long-term plan to build the world’s first large-scale, fault-tolerant quantum computer by 2029. ‘Theory and experiment are beginning to align’ Quantum computing utilises the ‘superposition’ and ‘destructive inference’ of matter in a quantum state, allowing for new forms of computing to solve problems across industries, beyond the scope of classical computers. Quantum computing promises huge advantages, but the fragile nature of quantum states mean that even the most minor issue can collapse a superposition into a classical state, removing the quantum advantage. “Any unintended interaction with the environment can destroy the very quantum effects that give [quantum computers] their power,” Williamson said. Williamson and Yoder’s research has detailed a new approach to error correction, which aims to overcome this fragility using so-called ‘gauge theory’. This effectively allows a system to keep track of global activity, like across a “quantum hard drive”, without forcing specific quantum states to collapse at the individual qubit level. “Gauge theory introduces additional degrees of freedom that track global properties without forcing the system into a definite local state,” Williamson said. “We realised a similar idea could be used to process logical quantum information. “A gauge is just a mathematical construct that provides a set of local coordinates for any

Lloyds Bank has been experimenting with quantum computing to improve financial crime prevention, in an early test of whether the technology can deliver practical benefits for banks. The bank tested whether quantum algorithms could spot money mule behaviour within a large collection of transactions, a task that traditional computers tend to struggle with due to the complexity of detecting subtle patterns within large-scale transaction data. The algorithms, which ran on one of IBM’s 156-qubit quantum computers, successfully identified a money mule — a bank account used to transfer stolen money — which had been deliberately placed within the data. “While quantum computing is still emerging, this experiment has allowed us to translate research into practical insights,” Ron van Kemenade, chief operating officer at Lloyds Banking Group, said. Quantum computing is a rapidly growing area of innovation. Researchers hope that it will be able to perform a number of tasks — such as cryptography and drug discovery — far more efficiently than classical computers. Whereas traditional computers process information as binary bits, either 0 or 1, the quantum equivalent — the qubit — can be both 0 and 1 at the same time, enabling the computer to explore multiple options simultaneously. Qubits can also become “entangled” with one another, which means different ones become very tightly correlated. When this happens, the measurement of one qubit can instantly reveal information about the other qubits with which it is entangled, allowing quantum computers to represent and manipulate complex relationships across many variables at once. Many existing models are prohibitively expensive, error-prone and highly sensitive to broader environmental factors, making them extremely challenging to build and scale, but the technology is seen as a huge potential growth area. According to Oxford Economics, quantum technology could add up to £212 billion to Britain’s GDP by

Lightning Network ‘Helplessly Broken’ Against Quantum Computers, Warns Udi Wertheimer Crypto analyst and Taproot developer Udi Wertheimer has stated that the Lightning Network is fundamentally vulnerable in a post-quantum scenario and claimed that its design leaves user funds exposed in ways that cannot be mitigated under current assumptions. According to Wertheimer, the core issue stems from how public and private keys function in cryptocurrency systems. While traditional cryptography relies on the idea that private keys cannot be derived from public keys, he explained that sufficiently advanced quantum computers, which are known as cryptographically relevant quantum computers (CRQCs), could break this assumption by calculating private keys directly from public ones. Lightning’s Weak Spot In most on-chain Bitcoin usage, users can reduce exposure by avoiding address reuse, which helps keep public keys from being exposed unnecessarily. However, Wertheimer argued that this defense does not apply to the Lightning Network, where public keys must be shared as part of its basic operation. Lightning relies on payment channels, which are essentially multi-signature arrangements between two parties. To open and maintain these channels, participants exchange public keys with counterparties. As a result, these keys are not only exposed but also stored by third parties, sometimes without users fully knowing who controls the infrastructure behind their channels. As such, if any entity holding these public keys gains access to a CRQC, or if such data is leaked to an entity that does, then private keys could be derived without user interaction, thereby enabling the theft of funds. Wertheimer further claimed that such an attack would not require the high-speed quantum capabilities often discussed in theoretical scenarios, as there would be no need to intercept transactions in real time. Instead, attackers could work offline using already available public key data. The problem is compounded by the opaque

Intel Capital has invested in Q-Factor, a quantum computing company aiming to build a million-qubit computer using neutral atom technology. Founded by physicists from the Weizmann Institute and the Technion, Israel Institute of Technology, Q-Factor secured $24 million in seed funding led by NFX and TPY Capital, alongside grants from the Israel Innovation Authority. The company intends to overcome limitations hindering current quantum computers, which remain too small to provide practical commercial value; Q-Factor’s approach focuses on scaling beyond the few thousand qubits currently achievable. “The quantum computing industry needs a substantial change, not just incremental improvements,” said Prof. Ofer Firstenberg, Q-Factor’s co-founder and chief scientist, asserting that incremental improvements will not bridge the gap to useful computation. Neutral Atom Architecture Targets Million-Qubit Scalability Q-Factor has secured $24 million in seed funding to pursue an ambitious goal: building a quantum computer capable of exceeding one million qubits. Unlike superconducting or trapped ion approaches, neutral atoms offer inherent advantages in coherence and control, utilizing light-based manipulation rather than relying on extreme cooling or intricate wiring. Despite these benefits, existing neutral atom platforms struggle to scale beyond a few thousand qubits, a critical barrier to achieving practical quantum computation. The founders of Q-Factor identified specific architectural bottlenecks preventing substantial increases in qubit count, leading them to develop a novel approach designed for continuous scalability. This is not simply about incremental improvements to existing designs; the team believes a fundamental shift is necessary to realize the full potential of quantum computing. Ofer Firstenberg, co-founder and chief scientist of Q-Factor, explained, “Current systems are too small to deliver on the promise of quantum computing, and incremental improvements alone aren’t going to close that gap. We’ve developed an architecture designed for continuous scalability, a trajectory that can take neutral atom systems from thousands of qubits

Abstract Hamiltonian simulation is a fundamental algorithm in quantum computing that has attracted considerable interest owing to its potential to efficiently solve the governing equations of large-scale classical systems. Exponential speedup through Hamiltonian simulation has been rigorously demonstrated in the case of coupled harmonic oscillators. The question arises as to whether Hamiltonian simulations in other physical systems also accelerate exponentially. Schrödingerization is a technique that transforms the governing equations of classical systems into the Schrödinger equation. However, since the Schrödinger equation is a linear equation, Hamiltonian simulation is often limited to linear equations. The research on Hamiltonian simulation methods for nonlinear governing equations remains relatively limited. In this study, we propose a Hamiltonian simulation method for nonlinear partial differential equations (PDEs). The proposed method is named Carleman linearization + Schrödingerization (CLS), which combines Carleman linearization (CL) and warped phase transformation (WPT). CL is first applied to transform a nonlinear PDE into a linear differential equation. This linearized equation is then mapped to the Schrödinger equation via WPT. The original nonlinear PDE can be solved efficiently by the Hamiltonian simulation of the resulting Schrödinger equation. By applying this method, we transform the original governing equation into the Schrödinger equation. Solving the transformed Schrödinger equation then enables the analysis of the original nonlinear equation. As a specific application, we apply this method to the nonlinear reaction–diffusion equation to demonstrate that Hamiltonian simulations are applicable to nonlinear PDEs.
