Quantum hardware has finally crossed a psychological threshold: it is no longer a science project in search of a purpose, it is a working tool that large companies and governments are starting to use.

The quantum layer will will not be exhausted by one hardware modality, one algorithmic framework or one vendor’s roadmap.

The agency is celebrating 2025 being designated as the International Year of Quantum Science and Technology with an educational campaign. Quantum science, and especially its most popular offshoot, ...

Google's quantum paper made headlines with that number. Here's what it means, what's actually at risk, and why 6.9 million ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...
