D-Wave's massive January acquisition of Quantum Circuits is paying off: way better error correction, making quantum computing ...

D-Wave is a bit of an oddity in the quantum computing space, having been founded back in the last century. And its initial ...

Four independent research teams report big advances in devices built with the underestimated quantum bits, including lower ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently ...

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits could simultaneously store more information than the number of particles in the ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

Researchers and tech companies are in a global race to develop quantum computers that can solve hard scientific problems that conventional computers can’t, and that they hope can eventually support ...

Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

The quantum threat is accelerating significantly. It's time to have a fresh look at the current state of affairs and what we're doing about it.
