The lower bound on the dimension of each share given by Gottesman [Phys. Rev. A \\textbf{61}, 042311 (2000)] is revisited based on a relation between the reversibility of quantum operations and the Holevo information. We also propose a threshold ramp quantum secret sharing scheme and evaluate its coding efficiency.", "revisions": [ { "version": "v1", "updated": "2005-04-30T10:54:30.000Z" } ], "analyses": { "keywords": [ "quantum operations", "secret sharing schemes encrypting", "reversibility", "ramp quantum secret sharing scheme", "threshold ramp quantum secret sharing" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
