摘　　要：本文我们将基于连续变量EPR纠缠态以及分束器算符的理论表达式提出四模连续变量完美最大纠缠态(CV PMES)的理论表达形式,在此基础上,进一步利用超导介观LC谐振子电路通过射频超导量子干涉仪进行耦合的系统,提出在实验上近似实现四模连续变量完美最大纠缠态的理论实现方案.In this paper, we proposed a way to obtain continuous-variable perfect maximally quadruple entangled states by applying beam splitter operations on continuous-variable EPR states. Then we show that the approximate version of these states can be achieved in circuit quantum electrodynamics systems composed of LC superconducting resonators and rf SQUIDs by tuning the applied flux bias to the rf SQUIDs.
