Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

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 ...

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

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

Quantum vendors and national agencies are aligning to establish common standards for logical qubits, which should enable ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

Researchers at the California Institute of Technology theorize that a functional quantum computer may require far fewer ...

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

A new theoretical study has taken a close look at how noise influences these circuits. The results show that noise places a ...

Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms.

Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment ...
