Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

Most of what a quantum computer does is not quantum. The processor that manipulates qubits sits in a chamber cooled to about 10 millikelvin, colder than outer space ...

Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, materials science, nuclear physics, and more. To make this future a reality, ...

Google has published research suggesting a future quantum computer could theoretically derive a bitcoin private key from its public key in about nine minutes, threatening the security of Bitcoin and ...

The promise of quantum computing has been building up year after year, and yet still seems as far away from practical reality as it has ever been. The good news is that there are finally end goals in ...

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.

John Martinis is a hardware guy. He prefers the nitty-gritty of doing physics in the lab over the idealised world of textbooks. But you couldn’t write the quantum computing history books without him: ...

Google LLC today published a paper that indicates a quantum computer with 500,000 qubits could be used to steal cryptocurrency. The cybersecurity risks posed by quantum computers were already ...

Software firm Horizon Quantum claimed it is the first private company to deploy a commercial quantum computer in Singapore. The deployment also makes it the first quantum software company to deploy ...
