环境诱导退相干和量子擦除过程中电子Mach-Zehnder干涉仪的量子路径可预测性

Quantum Path predictability for an electronic Mach-Zehnder interferometer in presence of environment induced Decoherence and Quantum Erasing process

Samyadeb Bhattacharya, Sisir Roy

摘要:

本文估计了电子马赫-曾德尔干涉仪的温度依赖路径可预报性。路径可预测性的增加可以直接与更强的退相干过程相关联。我们还从理论上预测,在两条路径中放置两个与系统处于相同平衡温度的探测器,会擦除路径信息的所有记忆,因此其作用就像量子橡皮擦。

英文摘要:

In this paper, we have estimated the temperature dependent path predictability for an electronic Mach-Zehnder interferometer. The increment of path predictability can directly be associated with stronger decoherence process. We have also theoretically predicted that placing two detectors in both the paths, which are at the same equilibrium temperature with the system, erases all the memory of path information and hence acts like a quantum eraser.
