Quantum Computing

IonQ’s claim that a 20,000-qubit machine could crack Bitcoin encryption within 26 days is a startling escalation and reignites fears about the most popular cryptocurrency and others too.

Nobody in Washington thought of quantum computing as a security problem twenty-five years ago.

Xanadu (NASDAQ/TSX: XNDU) and AMD have released Backline, a new solution designed to overcome a critical hurdle in quantum computing: establishing communication between quantum processors and classical hardware within microseconds.

On September 14, 2026, Quip Network will launch, marking the first time digital collectibles are generated directly by quantum processors and made available to consumers.

On Tuesday, D-Wave, Rigetti, Quantinuum, and PsiQuantum each locked in awards of up to $100 million under the CHIPS and Science Act. GlobalFoundries said the same day that it had closed its three hundred and seventy-five million dollar quantum foundry agreement. The cash comes from a May 21 package of $2.013 billion across nine companies. IBM and GlobalFoundries were picked to build wafer and chi…

IonQ reports a 20,000-physical-qubit quantum computer could break secp256k1, the cryptographic standard securing Bitcoin, in under 26 days. This estimate, detailed in a newly published paper, significantly accelerates timelines for potential cryptographic vulnerability previously projected for the 2030s. IonQ’s research team optimized the algorithm, compiler, hardware, and error-correction layer …

On the morning of 3 September 2026, Eric Lu posted a 130-digit integer on X and added four words: divides RSA-260. Eric apparently factored it, but we still do not know exactly how and are still waiting for an update. That was the paper. No lab announcement, no runtime, no cluster size. By afternoon, people had divided the published modulus on laptops, both factors had passed primality tests, and…

Between 1811 and about 1816, textile workers in the English Midlands and the North already worked at knitting frames that had existed since the 1500s. They rented them, paid the rent when orders were thin, and sold the work back to a clothing merchant. This way of working remained dominant until the rise of manufacturing models, or rather textile machines, that reduced the need for human interact…

NVIDIA CEO chief congratulated OpenAI on GPT-6 Astra and said the long-disputed milestone is here.

NEC has stopped development of a working quantum computer, the technology group revealed on September 5, 2026, after concluding that a return on investment would take too long, the company says.

Forschungszentrum Jülich and eleQtron have launched JION, a trapped-ion quantum computer built on ionized ytterbium atoms, a technology differing from superconducting systems that do not require operation at temperatures near absolute zero.

An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has, for the first time, observed the effect of gravity on a falling quantum object.

Five years ago this month, a quantum company rang the opening bell on a US exchange for the first time. That company was Arqit, a British quantum encryption firm briefly valued at close to $3 billion, now valued considerably less. Seven pure-play quantum computing companies have followed it onto American markets since, and between them they have produced a five-year record that deserves closer in…

An Oxford physicist argues Hilbert space is discrete and that Shor’s algorithm loses its advantage somewhere between 200 and 1,000 qubits. Musk’s nine-word reply on X sent the claim round the crypto press this weekend, and IBM’s 2029 machine will test it.

Pasqal is now a public company. The French neutral-atom developer began trading on Nasdaq on Friday, 28 August, under the ticker PSQL, with its warrants listed as PSQLW, and the shares closed the first session at 19.11 dollars, up from a reference price under 10 dollars for the shell it merged into. That is a near doubling on day one, a 2 billion dollar valuation on 16.5 million euros of 2025 rev…

On August 28, 2026, Pasqal’s ordinary shares will begin trading on Nasdaq under the ticker symbol “PSQL,” establishing a timeline for public investment in neutral-atom quantum computing.

Anthropic’s Claude, an AI agent, now recovers QuEra Computing’s laser system in seconds, a task previously requiring minutes of work from a human specialist.

Approximately 978,000 GPS jamming events were recorded globally in the first quarter of 2026, with 98% concentrated in the Middle East and impacting over 1,100 vessels; in response, Q-CTRL has demonstrated the world’s first GPS-free quantum gravimetric navigation system in a maritime field trial off Australia’s East Coast, the company says.

Infleqtion’s quantum processing unit is now powering “Shunkai,” Japan’s first operational full-stack neutral-atom quantum computer with an initial capacity of approximately 50 qubits and planned expansion to around 500.

Sparrow Quantum will outline a path toward large-scale photonic quantum computers with a four-month project funded by the EuroHPC Joint Undertaking’s Quantum Grand Challenge.
