单通道信息、熵和热流的普适量子极限

Universal quantum limits on single channel information, entropy and heat flow

Miles P. Blencowe, Vincenzo Vitelli

摘要:

我们发现,最近发现的普遍上限的热导率的一个单一的通道,包括粒子服从任意分数统计的结果,实际上是一个更普遍的普遍上限,涉及平均熵和能量流的一个单一的通道连接热源与任意温度和化学势。后者的上限反过来又导致,通过Holevo定理,一个普遍的(即,统计独立)上的最佳容量的上界经典的信息传输了一个单一的,宽带量子信道。

英文摘要:

We show that the recently discovered universal upper bound on the thermal conductance of a single channel comprising particles obeying arbitrary fractional statistics is in fact a consequence of a more general universal upper bound, involving the averaged entropy and energy currents of a single channel connecting heat reservoirs with arbitrary temperatures and chemical potentials. The latter upper bound in turn leads, via Holevo's theorem, to a universal (i.e., statistics independent) upper bound on the optimum capacity for classical information transmission down a single, wideband quantum channel.
