Insecurity of Quantum Two-Party Computation with Applications to Cheat-Sensitive Protocols and Oblivious Transfer Reductions

Autor: Hänggi, Esther, Winkler, Severin

Oblivious transfer (OT) is a fundamental primitive for secure two-party computation. It is well known that OT cannot be implemented with information-theoretic security if the two players only have access to noiseless communication channels, even in t

Quantum key distribution (QKD) is often, more correctly, called key growing. Given a short key as a seed, QKD enables two parties, connected by an insecure quantum channel, to generate a secret key of arbitrary length. Conversely, no key agreement is

Distilling Non-Locality

Autor: Forster, Manuel, Winkler, Severin, Wolf, Stefan

Publikováno v: Phys. Rev. Lett. 102, 120401 (2009)

Two parts of an entangled quantum state can have a correlation in their joint behavior under measurements that is unexplainable by shared classical information. Such correlations are called non-local and have proven to be an interesting resource for
