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 ...

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 ...

Designed to accelerate advances in medicine and other fields, the tech giant’s quantum algorithm runs 13,000 times as fast as software written for a traditional supercomputer. A quantum computer at ...

Peter Shor didn’t set out to break the internet. But an algorithm he developed in the mid-1990s threatened to do just that. In a landmark paper, Shor showed how a hypothetical computer that exploited ...

The FIDO2 industry standard adopted five years ago provides the most secure known way to log in to websites because it doesn’t rely on passwords and has the most secure form of built-in two-factor ...

Quantum computing is on the horizon, promising to solve complex problems beyond the capabilities of classical computers. But for Bitcoin and other cryptocurrencies, which rely on today’s cryptographic ...

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 ...
