No one yet knows which technology will power the quantum computers of the future, but the race to create them has already ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would take a classical computer an unreasonable amount of time to generate.

For decades, computers have become faster, smaller, and more powerful. But even the world’s best supercomputers have limits. Some calculations would take them thousands or even millions of years to ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

In 2025, German startup SAXON Q demonstrated a 4-qubit quantum computer that worked at room temperature. Now, the company is ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.
