A team led by the Shenzhen International Quantum Academy reports demonstrating logical operations on a silicon-based quantum ...

Chinese researchers have demonstrated a silicon quantum processor capable of performing a full set ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, ...

Another major quantum computing record has been broken, and by a considerable margin: physicists have now built an array containing 6,100 qubits, the largest of its type and way above the thousand or ...

Google published a paper on March 31 that states that Bitcoin's cryptography could be impacted by quantum computing sooner ...

Can a handful of atoms outperform a much larger digital neural network on a real-world task? The answer may be yes. In a ...

Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment ...

An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking work on quantum key cryptography.

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...
