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

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 ...

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

Quantum computers are expected to transform many facets of science and industry over the next decade or so – but it’s very ...

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.​ ...

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

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 ...

Picture a quantum computer. Are you imagining an ordinary computer, but somehow just better? If so, that would be a mistake, because quantum computers are fundamentally different. They rely on exotic ...

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