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 ...

Scientists have designed a physical qubit that behaves as an error-correcting "logical qubit," and now they think they can scale it up to make a useful quantum computer using a few hundred. When you ...

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