Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

When a quantum computer processes data, it must translate it into understandable quantum data. Algorithms that carry out this 'quantum compilation' typically optimize one target at a time. However, a ...

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many ...

A team from Amazon Web Services, NVIDIA, Lawrence Berkeley National Laboratory, and NASA published a paper this week that settles one of the most expensive open questions in quantum computing ...

Researchers from Google Quantum AI report that their quantum processor, Willow, ran an algorithm for a quantum computer that solved a complex physics problem thousands of times faster than the world's ...

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

A search problem refers to the task of finding a solution within some space of possible options, and that space could be made up of discrete steps or continuously varying values. For example, solving ...

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

It’ll still be a while before quantum computers become powerful enough to do anything useful, but it’s increasingly likely that we will see full-scale, error-corrected quantum computers become ...

Microsoft has updated a key cryptographic library with two new encryption algorithms designed to withstand attacks from quantum computers. The updates were made last week to SymCrypt, a core ...
