量子多用户检测是实现量子通信网络化和实用化的关键问题之一.结合经典多用户检测理论,分析了量子多用户检测的特点,建立了多用户量子通信信道模型,提出了一种量子多用户检测方案.该方案通过自适应调整测量算子实现多用户接收.通过对实际光纤量子信道的测量,验证了此方法的有效性,同时证明该方案具有降低测量误码率的优点.
For quantum communication,quantum multi-user detection must accomplish communication,so that quantum multi-user detection is a key point.In this paper,we note that the quantum multi-user detection differs from the classical one,construct a multi-user quantum communication channel model,and propose a new self-adaptive adjusting quantum detection scheme.This scheme is feasible and error rate is reduced by measuring the actual optical fiber channel.
