A multi-prover interactive proof for NEXP sound against entangled provers

We prove a strong limitation on the ability of entangled provers to collude in a multiplayer game. Our main result is the first nontrivial lower bound on the class MIP* of languages having multi-prover interactive proofs with entangled provers; namely MIP* contains NEXP, the class of languages decidable in non-deterministic ... more >>>

Perfect zero knowledge for quantum multiprover interactive proofs

In this work we consider the interplay between multiprover interactive proofs, quantum
entanglement, and zero knowledge proofs — notions that are central pillars of complexity theory,
quantum information and cryptography. In particular, we study the relationship between the
complexity class MIP$^*$ , the set of languages decidable by multiprover interactive ... more >>>

Practical Relativistic Zero-Knowledge for NP

In this work we consider the following problem: in a Multi-Prover environment, how close can we get to prove the validity of an NP statement in Zero-Knowledge ? We exhibit a set of two novel Zero-Knowledge protocols for the 3-COLorability problem that use two (local) provers or three (entangled) provers ... more >>>
