Quantum Computing

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.

WarpSpeed’s artificial intelligence has designed a quantum circuit that cracks a standard cryptographic challenge with significantly improved efficiency, the company says. The system achieved a 2.5 times more efficient circuit than Google’s in cracking the ECDSA challenge, a benchmark used to assess the security of digital signatures underpinning cryptocurrencies like Bitcoin and Ethereum, accord…

IBM and its partners report the first clear demonstrations of quantum advantage through three separate experiments, a milestone years in the making.

Quantinuum’s Helios will soon be accessible as a service within a US-based Oracle Cloud Infrastructure (OCI) AI data center.

Pasqal reports trapping individual atoms using laser light generated by a photonic integrated circuit, a first for neutral-atom quantum computing.

On July 9, 2026, a spectator examined TuringQ’s Gen2 large-scale hybrid integrated photonic quantum computer at the HIECO 2026 Intelligent Computing Application Conference in Zhengzhou, Henan Province; now, the Shanghai-based firm is seeking to become China’s first publicly listed quantum computing company. TuringQ entered IPO tutoring with the Shanghai branch of the China Securities Regulatory C…

D-Wave Quantum reports achieving 99.9% fidelity during two-qubit operations with a new entangling gate, a key step toward practical, fault-tolerant quantum computing.

IonQ (NYSE: IONQ) and Sandia National Laboratories have formalized a collaboration with a memorandum of understanding, committing to jointly develop quantum technologies for U.S.

Researchers at Imperial College London and The University of Hong Kong, Hong Kong SAR, China have demonstrated a quantum computing system using only light capable of supporting a universal gate set and enabling a broad range of quantum computing and simulation tasks.

A strategic plan released by a collaboration of researchers targets advancements in neutral atom technology, positioning the approach as a strong contender alongside other quantum computing modalities.

IBM shareholders have had a brutal few weeks, and if you have been following our coverage you saw most of it coming in stages. On 14 July the stock fell just over 25 percent in a single session, the worst day in at least 58 years of trading records and quite possibly the worst since the company’s predecessor listed in 1916, after CEO Arvind Krishna pre-announced second quarter numbers below conse…

Within the first weeks of Andy Burnham’s premiership, the government he now leads abolished the Department for Science, Innovation and Technology.

IBM has signed an agreement to acquire HRL Laboratories, a research and development institution jointly owned by Boeing and General Motors, in a move that ensures continued collaboration with both companies post-acquisition.

A startup less than a year old is challenging the conventional infrastructure demands of quantum computing; Zhongqi Wuliang unveiled the system at the World Artificial Intelligence Conference (WAIC) 2026, claiming it’s the first neutral atom quantum computer engineered for direct deployment in a standard server rack.

Come Monday, A new Prime-minister will govern the UK, but there are whispers Andy Burnham may dismantle DSIT
