Levy noted the system could make quantum a whole lot cheaper: SEEQC claims its methods reduce costs by 97% and energy usage by up to 100,000 times. Costs and energy consumption pose major roadblocks ...

A vexing problem has long confronted quantum computer designers: the need to keep bits in a superconducting quantum processor ...

Errors in quantum computers are an obstacle for their widespread use. But a team of scientists say that, by using an antimony atom and the Schrödinger's Cat thought experiment, they could have found a ...

Overall, beyond the competition between companies and qubit modalities - or focus on the contest to win the quantum race - is ...

D-Wave Quantum is working to redefine the competition. If QBTS succeeds, it might vault itself ahead of Rigetti Computing and ...

A breakdown of what type of risks quantum computing poses to Bitcoin, and how worried users of the network should be.

Nvidia CEO Jensen Huang's sobering assessment of quantum computing's timeline sent the space into a tailspin last week.

MIT researchers have achieved a world-record single-qubit fidelity of 99.998% using fluxonium, a superconducting qubit.

Quantum computing's potential hinges on overcoming errors. Advances in leakage correction and atom loss detection are key to achieving practical applications.

Nvidia CEO Jensen Huang may have said that "very useful quantum computers" are probably still 20 years away, but his company ...

Quantum computing promises to solve complex problems exponentially faster than a classical computer, by using the principles ...
