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.

At Gamescom 2026 in Cologne this week, Finnish game studio MiTale will debut C.L.A.Y., The Last Redemption, a post-apocalyptic RPG integrating quantum computing techniques into its story and environment generation.

Google Quantum AI researchers have determined that breaking the core cryptography of various cryptocurrencies, secured by the secp256k1 curve, may require as few as 1200 logical qubits and 90 million Toffoli gates, a significantly lower threshold than previously understood.

Coupled systems require complete quantisation to preserve relationships between position and momentum quantified by ħω representing energy in quantum fields. Analyses from Chiara Marletto London and Vlatko Vedral at the University of Oxford show combining classical and quantum descriptions introduces inconsistencies because

An agent’s status fundamentally relies on acknowledgement from other agents, defining a ‘mutually recognitive conception of agency’ according to new findings relating to QBism. The team reconstructed two formulations of this concept as it relates to Wigner’s friend paradox, revealing implicit connections to longstanding philosophical traditions. Agency, essentially who counts as making observatio…

Rolando D. Somma of Google Quantum AI and colleagues have devised a quantum algorithm that efficiently solves the Sylvester equation, a fundamental linear matrix equation used in fields from control theory to physics. The approach constructs a solution matrix using a technique that allows faster access to its properties than traditional methods of preparing a quantum state. The query and gate com…

The 1950s were the golden age of computing, and almost everything since has been a variation on what was settled then.

OTI Lumionics and the Samsung Advanced Institute of Technology have achieved quantum emulation of over 200 qubits using a single commercial AMD CPU chip with 32 processes and 800GB of RAM, reducing the hardware demands for quantum simulation, the company says.
