The idea that quantum computers might one day solve complex problems at lightning speed on microscopic chips has long been touted. But the race to show that these processors can outperform their ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

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