The paper develops a methodology for the design of coherent equalizing filters for quantum communication channels. Given a linear quantum system model of a quantum communication channel, the aim is to obtain another quantum system which, when coupled with the original system, mitigates degrading effects of the environment. The main result of the paper is a systematic equalizer synthesis algorithm which relies on methods of state–space robust control design via semidefinite programming.

利用鲁棒控制理论设计相干无源量子均衡器

该论文开发了一种用于量子通信信道的相干均衡滤波器设计的方法。给定量子通信信道的线性量子系统模型，目的是获得另一个量子系统，当与原始系统耦合时，可以减轻环境的退化影响。本文的主要成果是一种系统均衡器综合算法，该算法依赖于通过半定规划进行状态空间鲁棒控制设计的方法。
