Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have shown that they can fix the flubs ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

Months after a High Court judge tore into the Post Office’s approach to branch computer system errors, the organisation is not sharing details of possible errors with subpostmasters, who are also ...
