IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but proving quantum advantage in an absolute sense is difficult. All three ...

Four RIKEN researchers have used two small quantum computers to simulate quantum information scrambling, an important quantum-information process. This achievement illustrates a potential application ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

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.

The €4.6 million MSCA-backed QuBriC network brings together 16 universities and seven quantum companies to train 15 doctoral researchers in quantum error correction.

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...
