Universal fault-tolerant quantum computing relies on the implementation of quantum error correction. An essential milestone is the achievement of error-corrected ...

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 ...

Unlike binary bits of information in ordinary computers, “qubits” consist of quantum particles that have some probability of being in each of two states, designated |0 and |1 , at the same time. When ...
