量子高密度编码原理及其MATLAB仿真

由于没有实际操纵量子比特的条件,MATLAB以其简便的矩阵操纵手段和强大的科学计算功能,成为通信工程人员和在校学生学习量子通信基本原理的良好工具。给出了量子比特及其测定、量子序列、贝尔态基和常用量子逻辑门的MATLAB语言描述。分析了量子高密度编码原理,给出了MATLAB仿真程序。

Three-Particle Einstein-Podolsky-Rose Eigenstate and Its Application in QuantumDense Coding

We study the properties of the three-mode Einstein-Podolsky-Rose (EPR) eigenstate and its application in quantum dense coding. Our result shows that the three-mode EPR eigenstate provides a convenient way to realize quantum dense coding when the quantum channel is a three-mode squeezed state.
