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

摘要

In this paper, we have estimated the temperature dependent pathpredictability for an electronic Mach-Zehnder interferometer. The increment ofpath predictability can directly be associated with stronger decoherenceprocess. We have also theoretically predicted that placing two detectors inboth 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.
