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 ...

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

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, ...

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 ...

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 ...

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

Researchers from Caltech and Oratomic, a Caltech-linked startup, published findings on March 31, 2026, arguing that a useful quantum computer capable of running Shor’s algorithm on real cryptographic ...

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

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