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

TL;DR

This paper investigates how environmental decoherence affects path predictability in an electronic Mach-Zehnder interferometer and demonstrates that quantum erasing can eliminate path information, restoring coherence.

Contribution

It provides a theoretical analysis of temperature-dependent path predictability and introduces a quantum eraser setup in electronic interferometers.

Findings

Path predictability increases with decoherence

Quantum erasing restores interference by removing path information

Temperature influences decoherence and predictability

Abstract

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.
