Can Quantum Mechanics Help Distributed Computing? Anne Broadbent and Alain Tapp D partement d informatique et de recherche op rationnelle e e Universit de Montr al, C.P. 6128, Succ. Centre-Ville e e Montr al (QC), H3C 3J7, Canada e {broadbea,tappa}@iro.umontreal.ca Abstract We present a brief survey of results where quantum information processing is useful to solve distributed computation tasks. We describe problems that are impossible to solve using classical resources but that become feasible with the help of quantum mechanics. We also give examples where the use of quantum information signi cantly reduces the need for communication. The main focus of the survey is on communication complexity but we also address other distributed tasks. Keywords: pseudo-telepathy, communication complexity, quantum games, simulation of entanglement Quantum computation and entanglement This survey is aimed at researchers in the eld of theoretical computer science having only very limited knowledge of quantum computation. We address the topics of communication complexity and pseudotelepathy, as well as other problems of interest in the eld of distributed computation. The goal of this survey is not to be exhaustive but rather to cover many different aspects and give the highlights and intuition into the power of distributed
