Oh, the Places <b>Quantum</b> Might Go!

On a winter day in Wisconsin, you can watch chemistry at work. Road salt and moisture roughen a car’s frame. Steel structures slowly turn to rust. At the same time, we burn fuels that release carbon dioxide, and we rely on fertilizer to grow food — fertilizer that still takes a huge amount of energy to make. Corrosion, carbon capture and fertilizer sound like separate problems. In my research as a physicist, I think of them as three stops on the same road trip, because all three are controlled by the same tiny actors: electrons. Electrons decide whether metal stays strong or crumbles. They rearrange when a catalyst turns CO₂ into something useful. And they govern nitrogen chemistry, including the reactions that produce the nitrogen-containing compounds that modern agriculture depends on. In the above figure, you can see “Rusty Coast,” “Carbon Capture Crags” and “Nitrogen Valley,” with the swirling tornado of electron correlation halting our path to useful solutions. People are also reading… If we could reliably predict what electrons will do in complex materials and molecules, we could design better alloys, better catalysts and better chemical processes with far less trial and error. The catch is that electrons follow quantum mechanics. When many electrons interact strongly, the number of possibilities explodes, and even our best classical computers can struggle. Classical simulation tools are powerful and often spectacular, but some of the most important cases remain stubbornly hard. That is why I work on quantum computing for chemistry and materials. A quantum computer processes information using quantum effects. Because electrons are quantum, it’s natural to hope a quantum computer can simulate them more directly than a classical machine can. In the best cases, this could speed up calculations dramatically. But it’s not automatic. Today’s quantum devices are still at an

'It's the equivalent of Gulf oil': investors bet on UK sc...

The world is buying Britain’s brains. Isomorphic Labs, an AI drug-discovery company spun out of Google’s DeepMind, is in talks to raise another $2bn in funding from investors led by Thrive Capital. Quantum Motion, a spinout from Oxford University and UCL that builds quantum computers with silicon chips, closed a $160m financing round this week with funds from EU-backed tech fund Kembara and the British Business Bank (BBB). It is the largest early-stage raise in the UK’s quantum sector to date. But will betting on technological moonshots of this kind actually transform Britain’s growth prospects? “If the UK is going to build its first trillion-pound company, it will come out of one of the deep tech university ecosystems,” says Ed Bussey, chief executive of Oxford Science Enterprises (OSE). The firm – in which Oxford University holds a 5% “golden share” – is an early investor in Quantum Motion. Britain’s AI sector is gathering steam. But quantum – the mind-bending quest to build an exponentially more powerful computer that can instantly deliver scientific leaps forward in everything from GPS to drug discovery – hasn’t yet achieved commercial use. The geostrategic and financial stakes for Britain are huge. The UK government estimates quantum breakthroughs could boost productivity by 7% over the next two decades, creating more than 100,000 jobs and adding the combined annual output of Wales and Northern Ireland to GDP. It has announced more than £2bn of support for the sector, including funding from the BBB. “Despite the interest from the giants – Google and so on – there’s still uncertainty as to which approach is going to win overall,” says Quantum Motion’s co-founder John Morton. “There are lots of opportunities for companies, even at an early stage, to pick the right approach and get a really strong position in

China unveils 200-qubit Hanyuan-2 dual-core <b>quantum computer</b>

China unveils 200-qubit Hanyuan-2 dual-core quantum computer, consumes less than 7kW of power Hanyuan-2 is built around neutral atom technology. Chinese researchers claim that the launch of Hanyuan-2 represents a major step forward for the country’s quantum computing ambitions, with state media describing the system as evidence that China’s quantum technology is moving into a new phase of development. Unlike many existing quantum computers that require enormous energy consumption and ultra-cold environments near absolute zero to function, Hanyuan-2 is built around neutral atom technology, which is considered more energy efficient and easier to operate and maintain. The system’s most notable feature is its dual-core architecture, which allows the two quantum processing units to work simultaneously, similar to two interconnected brains. According to Chinese media reports, the paired cores can split computational workloads between them while also helping identify and correct errors during processing, potentially improving both speed and reliability. Hanyuan-2 focuses on real-world industrial applications Developed by CAS Cold Atom Technology, a company linked to the Chinese Academy of Sciences and headquartered in Wuhan, Hanyuan-2 represents China’s latest attempt to accelerate the transition of quantum computing from experimental research into practical industrial use, the South China Morning Post reports. Quantum computers rely on qubits, or quantum bits, which allow them to process information in ways that are far beyond the capabilities of traditional computers when handling certain highly complex tasks. However, scaling these systems remains one of the industry’s biggest technical challenges. Researchers around the world continue to face difficulties in managing millions of qubits reliably, leading many companies and laboratories to prioritize more achievable near-term applications using systems built with dozens or hundreds of qubits instead of massive large-scale architectures. Rather than pursuing extremely large-scale systems, Hanyuan-2 focuses on improving the performance and stability of a more manageable quantum

IonQ Stock Fell 9% After a Record Earnings Beat. Here's What the Market Missed.

Key Stats for IonQ Stock - Current Price: $47.68 - Target Price (Mid): ~$145 - Street Target: ~$65 - Potential Total Return: ~205% - Annualized IRR: ~27% / year - Earnings Reaction: -9.30% (May 7, 2026) Now Live: Discover how much upside your favorite stocks could have using TIKR’s new Valuation Model (It’s free) >>> What Happened? Quantum computing stocks have spent much of 2026 being sold despite strong execution. IonQ (IONQ) reported its largest quarter on record on May 6, beat revenue estimates by 30%, and raised full-year guidance. In the next session, the stock fell 9.30%. Bulls argue the selloff was a “sell the news” overreaction driven by a misleading EBITDA headline. Bears argue a company with free cash flow projected negative through 2029 and no profitability before 2030 was never cheap at $47. The question investors are asking now: did the market overreact, and does the selloff create an opportunity? The answer depends on which number you focus on. The Quarter Behind the Drop On May 6, 2026, IonQ reported $64.7 million in GAAP revenue for Q1 2026, representing 755% year-over-year growth, against a year-ago figure of $7.57 million. The result beat the Wall Street consensus of $49.73 million by 30%. Management raised full-year guidance to $260–$270 million and guided Q2 to $65–$68 million. The selloff came from the adjusted figures. Adjusted EBITDA (a measure of operating profitability excluding non-cash items) came in at a loss of $96.8 million, worse than the ($79.87 million) consensus. Adjusted EPS landed at ($0.34), missing the ($0.25) estimate. The stock fell 9.30% on May 7. What the headline missed: $12 million of the $96.8 million EBITDA loss came directly from IonQ’s commercial agreement with SkyWater Technology, whose acquisition IonQ announced in January 2026 and expects to close in Q2 or Q3

FrostByte Secures €1.3M ($1.5M USD) to Scale Cryo-CMOS Control Electronics for ...

Graduate Ventures, a Dutch early-stage investment firm, has celebrated its 80th investment by backing FrostByte, a Delft-based quantum startup specializing in cryogenic control electronics. The investment is part of a €1.3 million ($1.5 million USD) funding round that includes participation from InnovationQuarter Capital, UNIIQ, Paeonia Group, and an undisclosed angel investor. Reaching this milestone exactly five years after its 2021 launch, Graduate Ventures has solidified its position as one of the most active pre-seed and seed investors in the Netherlands, focusing on TU Delft, Erasmus University Rotterdam, and Erasmus MC spin-offs. Cryo-CMOS Technology for Scalable Quantum Systems FrostByte, a spin-off from TU Delft and QuTech, addresses one of the primary scaling bottlenecks in quantum computing: the “cabling and heat” challenge. As quantum processors scale to millions of qubits, the traditional method of keeping control electronics at room temperature—connected via massive bundles of coaxial cables—becomes physically impossible due to heat generation and space constraints. FrostByte develops specialized cryo-CMOS (Complementary Metal-Oxide-Semiconductor) chips and cryogenic switches designed to operate inside the dilution refrigerator at temperatures near absolute zero (4 K and below). By moving the control architecture closer to the quantum processor, FrostByte aims to make quantum systems significantly more compact, power-efficient, and scalable. Industrializing Fundamental Research The startup is led by co-founders James Kroll (CEO) and Luc Enthoven (CTO), with scientific support from Fabio Sebastiano and Masoud Babaie, both internationally recognized pioneers in cryogenic integrated circuits. The capital from this round will be used to expand the team and accelerate the transition from academic research to manufacturable hardware. FrostByte’s roadmap includes scaling the production of its proprietary cryogenic switches and developing integrated circuits that can control and read out quantum devices locally. This “short-wire” approach is essential for the transition from laboratory prototypes to the industrial-scale quantum computers required for drug discovery,

Chinese company launches 4th-generation superconducting <b>quantum computer</b> ...

The "Origin Wukong-180" quantum computer Photo: Sun Chao Chinese company Origin Quantum's self-developed fourth-generation "Origin Wukong-180" superconducting quantum computer officially went online on Saturday and has begun accepting quantum computing tasks from around the world, its developer told the Global Times. The developer said the latest breakthrough marks the first systematic integration of China's independently developed quantum computing power into the artificial intelligence (AI) application ecosystem, representing a key step in advancing China's self-developed quantum computers from being "usable" to becoming "practical and accessible." The computer is equipped with a single-core 180-qubit superconducting quantum chip, achieving 100-qubit-level quantum computing capability under a single-chip architecture. There is a major leap in technology and computing power in the new version, compared with the previous one. Its four key systems â the quantum computing chip system, quantum computing measurement and control system, quantum computing environment support system, and quantum computer operating system â were all independently developed, Origin Quantum said. The predecessor, the superconducting quantum computer "Origin Wukong," was equipped with a single-core 72-qubit quantum chip and went online on January 6, 2024. The system has now operated stably for more than two years, receiving about 50 million remote visits from users across more than 160 countries and completing more than 900,000 global quantum computing tasks. In 2025, it also achieved China's first overseas export sale of independently developed quantum computing power, said the company. On April 20, Origin Quantum announced that the "Origin Wukong" had initially gained the capability to support AI computing and had launched multiple quantum AI tools, including the quantum knowledge large model Origin Brain and QPanda3 Runtime MCP.

<b>Quantum Computers</b> Could Soon Talk to Each Other Using Sound

A phonon is absurdly small. The quantum of vibrational energy, the irreducible minimum of sound, it carries no mass and lives only briefly before dissolving back into the thermal noise of whatever material surrounds it. For quantum engineers trying to build the next generation of computing hardware, that brevity has long been the problem. You cannot build an information highway out of something that barely exists. And yet a team at Harvard has just demonstrated that a single phonon, one solitary packet of vibration humming through a sliver of engineered diamond, can reach inside an atomic defect and change its quantum state. The implications go considerably beyond the neat physics of the thing. The result, published in Nature, marks the first observation of what physicists call the acoustic Purcell effect at the level of a single spin qubit, and it plants a flag in a field that has been trying to get here for the better part of a decade. To understand why it matters, it helps to think about the problem quantum engineers are actually trying to solve. Today’s most capable quantum processors, whether they are built from superconducting circuits or from atomic defects in crystals, tend to be brilliant in isolation and terrible in conversation. Getting one type of qubit to hand quantum information to another is roughly like trying to get two musicians playing in different keys to improvise together without a shared instrument. Light has been the obvious candidate for connecting them, but light carries its own complications: it is hard to confine, easy to lose, and not every qubit talks to it naturally. Sound, it turns out, might offer something better. Marko Loncar, who leads the Harvard group, put it directly: “At the heart of the experiment is a phonon, the smallest possible unit of

<b>Quantum computing</b> could expose $3T in digital a... | Pluang – Crypto, Stocks, Gold &amp; Funds

A new 110-page report by Project Eleven warns that quantum computers could break the cryptography securing over $3 trillion in digital assets, including Bitcoin and Ethereum, by as early as 2030 and no later than 2033. This threat extends beyond cryptocurrencies to banking systems, cloud infrastructure, and military communications. Migrating to post-quantum cryptography is complex, requiring coordinated action across users, exchanges, and institutions, and could take a decade or more. The report highlights the urgency and coordination challenges, especially for Bitcoin, whose upgrades historically move slowly and involve political debates.

Shorter <b>Quantum</b> Circuits Accurately Model Molecular Reactions Using Variation

Scientists at the University of Georgia have developed a new method for efficiently simulating molecular dynamics using quantum computers. Joshua M. Courtney and P. C. Stancil demonstrate variational compression of quantum circuits, enabling the approximation of nonadiabatic dynamics with shallower, more hardware-compatible circuits. The method preserves key observable quantities, specifically reaction rate coefficients, through a hybrid quantum-classical optimisation method and fast-forwarded adiabatic dynamics. By compressing circuits and incorporating them into product-formula-based time evolution, the team achieved tunability in removing computationally expensive qubit interactions, representing a vital step towards simulating complex quantum systems with limited resources. Variational compression streamlines quantum simulation of molecular reaction rates A five-fold reduction in the number of quantum gates needed to simulate molecular dynamics has been achieved, surpassing the limitations of previous methods hampered by circuit depth. This reduction is particularly significant given the inherent limitations of current quantum hardware, where gate fidelity decreases with increasing circuit complexity. Enabled by variational compression of ‘Trotter terms’, a standard technique for evolving quantum states in time, this breakthrough allows circuits approximating particle behaviour in coupled harmonic potentials to be created. This was a feat previously impossible without excessive computational cost. The challenge lies in accurately representing the potential energy surface of molecules, which often requires deep quantum circuits to achieve the necessary precision. Previous approaches struggled with the exponential growth of circuit complexity as the system size increased, leading to intractable simulations. Tunable circuits removing high-cost qubit interactions were demonstrated by preserving reaction rate coefficients through classical emulation and fast-forwarded adiabatic dynamics; this is a key step towards simulating complex chemical systems, including those relevant to catalysis, photochemistry, and materials science. The ability to accurately model these systems could lead to the design of more efficient catalysts, improved solar cells, and novel materials with tailored properties. The compressed

<b>Quantum Computers</b> Threaten $3 Trillion in Digital Assets | Whalesbook

The Growing Quantum Threat to Digital Assets Project Eleven's latest report issues a grave warning: over $3 trillion in digital assets could be vulnerable to theft within the next four to seven years. This widespread risk arises because current digital signatures, like those used in cryptocurrencies, can be broken by powerful quantum computers. The report, "Post-Quantum Security and Migration for Digital Assets," states that "Q-Day"—when quantum computers can crack widely used encryption—could arrive as early as 2030. Why This Threat is So Serious The global cryptocurrency market is currently valued at around $2.7 trillion, with Bitcoin alone exceeding $1.6 trillion. The cryptography securing this value, primarily elliptic curve digital signatures, is theoretically vulnerable to quantum machines using Shor's algorithm. This isn't just a crypto problem; it affects critical financial systems, cloud services, and secure communications, creating a risk of widespread disruption. The report emphasizes the biggest obstacle isn't technology but a severe lack of global cooperation, urgency, and funding for the necessary migration to quantum-resistant encryption. Upgrading complex systems can take five to over ten years, a timeline that directly clashes with Q-Day's potential arrival, leaving a dangerous window for attackers. Crypto Giants Begin Quantum Migration Efforts Major blockchain networks are beginning their preparations. The Ethereum Foundation has researched post-quantum cryptography since 2018 and aims for core infrastructure readiness by 2029, exploring hybrid schemes and account abstraction for gradual adoption. They recognize that current signatures (ECDSA, BLS, KZG commitments) will need upgrades. Solana's Foundation, working with validator clients Anza and Firedancer, is focusing on the Falcon digital signature scheme for a phased rollout. Cardano and Polkadot are also conducting research and development. Regulators are also stepping in. The G7 Cyber Expert Group published a roadmap in January 2026 targeting critical system migration by 2030-2032. Global cybersecurity spending is set to

Project Eleven warns Bitcoin faces <b>quantum</b> threat by 2030

Project Eleven warns Bitcoin faces quantum threat by 2030 A new report estimates 6.9 million BTC are vulnerable to quantum attacks, and the window for migration may be closing faster than anyone expected. Here’s a thought experiment that should keep Bitcoin holders up at night: what happens when a machine can crack the cryptography protecting your wallet in minutes instead of millennia? According to quantum computing research firm Project Eleven, that scenario isn’t science fiction anymore. It’s a planning horizon. The firm’s latest report argues that quantum computers could breach the encryption underpinning Bitcoin by 2030, putting roughly 6.9 million BTC at direct risk. At current prices, that’s approximately $560 billion worth of Bitcoin sitting in addresses with exposed public keys, essentially waiting for a sufficiently powerful quantum computer to come along and pick the lock. The vulnerability, explained The 6.9 million BTC figure comes from older address formats that expose public keys directly on the blockchain. Newer address types, like those starting with “bc1,” hash the public key before recording it on-chain, adding a layer of protection. But millions of coins, including some believed to belong to Bitcoin’s pseudonymous creator Satoshi Nakamoto, sit in legacy addresses where the public key is visible to anyone who cares to look. Project Eleven’s report estimates a greater than 50% likelihood that quantum computers will be capable of breaking these protections by 2033. The 2030 date represents a more aggressive but plausible timeline, depending on the pace of hardware breakthroughs. Why “gradual” isn’t how this works One of the more unsettling arguments in the report is that quantum computing progress won’t arrive like a slowly rising tide. It’s more likely to come in explosive bursts. Recent research has validated cracking a 15-bit elliptic curve key using quantum methods. That sounds impressive until you
