Abstract

We investigate whether certain non-classical communication channels can be simulated by a classical channel with a given number of states and a given 'amount' of noise. It is proved that any noisy quantum channel can be simulated by a corresponding classical channel with 'the same amount' of noise. Classical simulations of general probabilistic channels are also studied.
