A Quantum Measurement Scenario which Requires Exponential Classical Communication for Simulation

Abstract

In this paper we consider the following question: how many bits of classical communication and shared random bits are necessary to simulate a quantum protocol involving Alice and Bob where they share k entangled quantum bits and do not communicate at all. We prove that 2^k classical bits are necessary, even if the classical protocol is allowed an εchance of failure.
