A high-performance silicon-based quantum processor has been developed in which the spins of nine phosphorus nuclei — divided into two groups, or registers — and two shared electrons act as quantum ...

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link ...

Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the ...

The quantum computing industry is advancing, but is it advancing fast enough? While we constantly hear claims like a quantum computer could be 20,000 times faster, the actual physical processors — the ...

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

Quantum computer could break Bitcoin cryptography with under 500,000 qubits in nine minutes. This will likely only be ...

IBM on Tuesday announced a detailed roadmap to develop a large-scale, fault-tolerant quantum computer called Quantum Starling. Part of the company's plan involves the new IBM Quantum Nighthawk ...

Google's Willow quantum computer processor was able to map out the features of a molecule 13,000 times faster than a modern supercomputer. Researchers at tech giant Google said they mapped out the ...
