论文摘要
我们从量子信息理论的角度研究了带有不对称束分离器的一般马赫 - 齐汉德干涉仪中的波颗粒二元性。当粒子和颗粒探测器处于纯状态或混合状态时，在马赫 - 齐汉德干涉仪的输出处，粒子和哪个路径检测器之间的相关性（包括经典的相关性和量子相关性）。发现边缘可见性和相关性是由不对称的束分离器和粒子的输入状态实现的。还提出了附带可见性与相关性之间的互补关系。
We study the wave-particle duality in a general Mach-Zehnder interferometer with an asymmetric beam splitter from the viewpoint of quantum information theory. The correlations(including the classical correlation and the quantum correlation) between the particle and the which-path detector are derived when they are in pure state or mixed state at the output of Mach-Zehnder interferometer. It is found that the fringe visibility and the correlations are effected by the asymmetric beam splitter and the input state of the particle. The complementary relations between the fringe visibility and the correlations are also presented.
