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 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 ...

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 ...

Irrational numbers have underpinned quantum mechanics for a century. Removing them could eliminate its strangest features and ...

Algorithms for quantum computers to break conventional encryption in particular are making progress, which is why cryptologists are looking for ways to encrypt communication in such a way that the new ...
