Quantum error correction for various forms of noise
Julio R. Gea-Banacloche, James Clemens · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2004
Quantum error correction will be an indispensable ingredient of large-scale quantum computations. Conventional quantum error correction codes (QECC) have been devised with an independent-error model in mind, but one may expect that the noise affecting a system of qubits will, in general, exhibit nonzero correlations in time, or space, or both. This talk will present a brief introduction to the principles of quantum error correction, followed by a discussion of the performance of conventional QECCs in the presence of correlated noise.
