Simple necessary and sufficient conditions for an ideal quantum operation to be reversible by a unitary operation are derived in this paper. These results generalize recent work on reversible measurements by Mabuchi and Zoller [Phys. Rev. Lett. {\\bf 76}, 3108 (1996)]. Quantum teleportation can be understood as a special case of the problem of reversing quantum operations. We characterize completely teleportation schemes of the type proposed by Bennett {\\it et al.} [Phys. Rev. Lett. {\\bf 70}, 1895 (1993)].", "revisions": [ { "version": "v1", "updated": "1996-08-01T18:59:06.000Z" } ], "analyses": { "keywords": [ "reversible quantum operations", "application", "ideal quantum operation", "general description", "quantum mechanics" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
