Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

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 ...

Quantum information protocols are inevitably affected by noise, which in turn produces errors in the extremely sensitive processed quantum information 1. To take full advantage of quantum information ...
