Non-Markovianity through quantum coherence in an all-optical setup

Year: 2019

Type: article

Abstract: We propose an all-optical experiment to quantify non-Markovianity in an open quantum system through quantum coherence of a single quantum bit. We use an amplitude damping channel implemented by an optical setup with an intense laser beam simulating a single-photon polarization. The optimization over initial states required to quantify non-Markovianity is analytically evaluated. The experimental results are in very good agreement with the theoretical predictions.
