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 ...

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently ...

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 ...

The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and ...

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 ...

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

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 ...

MIT’s Peter Shor explains why he devised an algorithm for a quantum computer that could unravel our online data encryption Internet security relies on the fact that our computers can’t break its ...

Quantum computing will reshape encryption, but not overnight, and a disciplined, phased approach lets organizations modernize cryptographic foundations without disruption while strengthening security ...

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