Phys. Rev. A 59, 162–168 (1999)Quantum entanglement for secret sharing and secret splittingReceived 28 July 1998; published in the issue dated January 1999 We show how a quantum secret sharing protocol, similar to that of Hillery, Buzek, and Berthiaume (Los Alamos e-print archive quant-ph/9806063), can be implemented using two-particle quantum entanglement, as available experimentally today. We also discuss in some detail how both two- and three-particle protocols must be carefully designed in order to detect eavesdropping or a dishonest participant. We also discuss the extension of a multiparticle entanglement secret sharing and splitting scheme toward a protocol so that m of n persons with m<~n can retrieve the secret. © 1999 The American Physical Society URL:
