摘要
量子通信是目前物理学和信息学科研究的热门领域,文章从量子通信的物理基础出发,研究了通信双方对信息的处理方法和信息的传输过程,从理论上分别计算了在4个Bell基下传输实体的量子态的变化和接收者的幺正变换矩阵;给出了实现通信的量子线路,并以该线路为基础计算了Bell基及对应的幺正变换矩阵和量子门.
Quantum communication is a fashionable field of physics and informatics at present.Starting with the theoretical basis of quautum communication,the author investigats the method of dealing with information and the process of carrying information for both sides of communication.The variety of quantum state of transfers' particle and unitary transformation matrix of acceptant are calculated in theory by four Bell radix.The circuitry of quantum communication is provided,and the author obtains Bell radix and quantum gate for corresponding unitary transformation matrix by the circuitry.
