2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/102067We give a short introduction to operator quantum error correction. This is a new protocol for error correction in quantum computing that has brought the fundamental methods under a single umbrella, and has opened up new possibilities for protecting quantum information against undesirable noise. We describe the various conditions that characterize correction in this scheme.To appear in Proceedings of the 25th Meeting of the Great Plains Operator Theory SymposiumOperator AlgebrasFunctional AnalysisQuantum Physicstext
