New classical simulation technique makes it practical to benchmark large-scale logical magic-state preparation protocols under realistic noise conditions ...

Quantum computers have the potential to outperform conventional computers on some tasks, including complex optimization problems. However, quantum computers are also vulnerable to noise, which can ...

A team of physicists, computer scientists and information machine specialists at Harvard University, working with colleagues from QuEra Computing Inc., the University of Maryland and MIT, has created ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits ...
