Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough ...

Quantum mechanics would allow the Universe to eventually tunnel to the lowest energy state, or the ‘true’ vacuum, and that process would result in a cataclysmic global event. (CREDIT: Professor Zlatko ...

Fujitsu quantum researcher Shinji Kikuchi discusses the quantum computing paradigm shift expected around 2030, as well as how ...

The system is currently performing at a 99.1% median two-qubit gate fidelity with a gate speed of ~60 ns and a 99.9% median single-gate fidelity. Rigetti is releasing Cepheus-1-108Q now in response to ...
