For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

To shrink error rates in quantum computers, sometimes more is better. More qubits, that is. The quantum bits, or qubits, that make up a quantum computer are prone to ...

A team of computer engineers from quantum computer maker Quantinuum, working with computer scientists from Microsoft, has found a way to greatly reduce errors when running experiments on a quantum ...

The company’s surface code technique allows its quantum bits to faithfully store and manipulate data for longer, which could pave the way for useful quantum ...
