Shares of Rigetti Computing were higher Wednesday after the company said it had achieved its mid-year milestone of reducing the error rate for one of its quantum computing systems. The stock was up 13 ...

The quantum computing revolution draws ever nearer, but the need for a computer that makes correctable errors continues to hold it back.

Quantum computing will not deliver truly useful business results overnight, but the pace of progress is no longer linear; ...

In a pair of papers submitted June 17 at arXiv.org, researchers generated conditions called “magic states,” crucial components of quantum computations. And those magic states were high-quality enough ...

Atom Computing builds scalable quantum computers. A quantum computer, compared with traditional, familiar computers, pack magnitudes more computing power to be able to solve complex problems.

Quantum computing is advancing with superconducting chips, simulators and a hybrid model bridging today’s systems with future hardware.

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems.

Cloud quantum supremacy Amazon (NASDAQ: AMZN) leverages its dominant Amazon Web Services (AWS) cloud infrastructure to democratize quantum computing through Braket, offering developers access to ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert ...

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers.
