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.

通信渠道的经典模拟

我们研究是否可以通过具有给定状态数量和给定“数量”噪声的经典通道来模拟某些非经典通信通道。事实证明，任何有噪声的量子通道都可以通过具有“相同数量”噪声的相应经典通道来模拟。还研究了一般概率通道的经典模拟。
