A new facility in Queensland will allow researchers from academia and industry to test new ideas on a real quantum processor.

The race to build larger and more powerful quantum computers has mostly focused on engineering: adding more qubits, reducing noise, and keeping fragile quantum states alive. However, a new theoretical ...

Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give ...

A new mathematical test shows that many seemingly useful quantum states can still be simulated classically, raising the bar ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university blackboards: a quantum computer. These days, quantum computers—which ...

Quantum computing should be viewed as a powerful new tool for solving specific classes of exceptionally difficult problems.​ ...

Every week quantum computing hits a new milestone: more qubits, fewer errors, better readout of results. But will these breakthroughs help solve the advanced computational problems facing energy, like ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

I founded Xanadu to build the world’s first scalable quantum computer. Keeping the industry here may be even harder.

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.
