Scientific paper

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 \epsilon chance of failure.
