Quantum cryptographic three party protocols
J. Mueller-Quade, H. Imai
Due to the impossibility results of Mayers and Lo/Chau it is generally thought that a quantum channel is cryptographically strictly weaker than oblivious transfer. In this paper we…

Temporary Assumptions for Quantum Multiparty Secure Computations
J. Mueller-Quade, H. Imai
This paper introduces quantum multiparty protocols which allow the use of temporary assumptions. We prove that secure quantum multiparty computations are possible if and only if cl…
