摘要

在香农信息理论中，无记忆通信信道的容量不能通过使用反馈来增加。当在非纠缠输入状态中使用反馈时，或者当通道是纠缠打破通道时，使用经典反馈不会增加无记忆量子通道的经典容量

On feedback and the classical capacity of a noisy quantum channel

In Shannon information theory the capacity of a memoryless communication channel cannot be increased by the use of feedback. The use of classical feedback is shown to provide no increase in the classical capacity of a memoryless quantum channel when feedback is used across nonentangled input states, or when the channel is an entanglement-breaking channel
