Quantum computers might break Bitcoin security faster than thought

Google researchers have revealed that breaking RSA encryption—the technology securing crypto wallets—requires far fewer quantum resources than previously thought. The team found cracking 2048-bit RSA could take under a week using fewer than a million noisy qubits, 20 times less than previously estimated.

Currently, quantum computers like IBM’s Condor and Google’s Sycamore operate with far fewer qubits, so crypto assets remain safe for now. The significance lies in the rapid pace of improvement in quantum computing capabilities, which calls for increased vigilance.

The breakthrough stems from improved algorithms that speed up key calculations and smarter error correction methods. Researchers also enhanced ‘magic state cultivation,’ a technique that boosts quantum operation efficiency by reducing resource waste.

Bitcoin relies on elliptic curve cryptography, similar in principle to RSA. If quantum computers can crack RSA sooner, Bitcoin’s security timeline could be shortened.

Efforts like Project 11’s quantum Bitcoin bounty highlight ongoing research to test the threat’s urgency.

Quantum threats extend beyond crypto, affecting global secure communications, banking, and digital signatures. Google has begun encrypting more traffic with quantum-resistant protocols in preparation for this shift.

Despite rapid progress, challenges remain. Quantum computers must maintain stability and coherence for long periods to execute complex operations. Currently, this remains a major hurdle, so there is no immediate threat.

It seems likely the first quantum-resistant blockchain upgrades will arrive well before any quantum attack on Bitcoin’s network.

Quandela presents Belenos, a powerful 12-qubit quantum computer

French quantum computing startup Quandela has unveiled Belenos, a 12-qubit photonic quantum computer that it claims delivers 4,000 times more computing power than its predecessor.

The first integrated version is set to be delivered to EuroHPC/GENCI and operated at the CEA’s Très Grand Centre de Calcul (TGCC) before the end of 2025.

Currently, Belenos is accessible via the cloud to over 1,200 researchers across 30 countries in Europe, North America, and Asia.

Instead of relying solely on local deployments, this cloud availability enables researchers to explore hybrid HPC-quantum use cases in fields such as structural mechanics, meteorology, and materials science.

Quandela has ambitious plans to double the qubit count by 2026 with the launch of Canopus. Within three years, the company aims to develop a photonic quantum computer with more than 40 qubits, continuing its focus on systems that avoid cryogenic cooling by using photonics-based methods instead.

‘Our cloud-accessible Belenos system lets partners work on tasks where computing speed and operations per data point are crucial — areas where competitors fall short,’ said co-founder and CEO Niccolo Somaschi.

The platform is designed for practical applications in machine learning and at the AI-quantum interface, which Quandela views as strategically vital sectors for the future.

New quantum method mimics molecular chemistry efficiently

Researchers have used a single atom to simulate how molecules react to light, marking a milestone in quantum chemistry.

The experiment, carried out by a team at the University of Sydney and published in the Journal of the American Chemical Society on 14 May, could accelerate the path to a quantum advantage, where quantum simulations outperform classical computing methods.

Instead of relying on multiple qubits, the team used a single ytterbium ion confined in a vacuum to mimic the complex interactions within organic molecules such as allene, butatriene and pyrazine.

The molecules react to photons through a series of electron and atomic movements, which are difficult to model using conventional computing when the number of vibrational modes increases.

The researchers encoded electronic excitations into the ion’s internal states and its motion along two directions in the trap, simulating molecular vibrations. By manipulating the ion with lasers, they emulated how the molecules behave after absorbing a photon.

The team then measured changes in the ion’s excited state over time to track the simulation’s progress. The method’s accuracy was validated by comparing results with known behaviours of the molecules.

While these specific molecules can still be simulated with traditional methods, the team believes their hardware-efficient approach could model more complex chemical systems using only a few dozen ions, rather than millions of qubits.

Experts, including quantum chemist Alán Aspuru-Guzik and Duke University’s Kenneth Brown, praised the work as a significant advance in quantum simulation.

Microsoft adds quantum-resistant encryption to Windows 11

Microsoft is rolling out quantum-resistant encryption algorithms in Windows 11 as part of its effort to prepare for the eventual arrival of quantum computers. The new cryptographic tools were announced at the BUILD 2025 conference and are now available in Insider Preview Build 27852 and higher.

These updates introduce post-quantum algorithms—ML-KEM and ML-DSA—into SymCrypt, Windows’ core cryptographic library.

The algorithms, formerly known as CRYSTALS-Kyber and CRYSTALS-Dilithium, were selected by the US National Institute of Standards and Technology (NIST) and are part of the agency’s recommended post-quantum cryptography (PQC) standards.

The algorithms have also been added to SymCrypt-OpenSSL, Microsoft’s open-source extension for integrating SymCrypt with OpenSSL. Developers can now access the algorithms via Microsoft’s Cryptography API: Next Generation (CNG), enabling early testing and migration.

Quantum computers, which are still in experimental stages, promise to outperform classical systems in solving problems like factoring large numbers—a cornerstone of traditional encryption methods like RSA and elliptic curve cryptography.

Experts warn that these legacy systems could be broken in the coming decades, potentially compromising the security of global communications, financial systems, and data infrastructure.

The new PQC algorithms are designed to resist quantum attacks, but they bring additional complexity. Their encryption keys are significantly larger than those used in current standards.

For now, NIST recommends using them alongside RSA or elliptic curve keys in hybrid configurations, to mitigate risks from undiscovered vulnerabilities.

The transition to quantum-safe encryption is expected to be one of the most complex in cybersecurity history. Developers will need to address compatibility issues, including ensuring software can handle longer key lengths without introducing system-breaking errors.

Microsoft’s early adoption is a step toward broader post-quantum readiness. Experts emphasize the importance of rigorous testing now, as the timeline for quantum threats remains uncertain.
