Abstract

In this paper, we investigate the exact decoherence dynamics of a superconducting resonator coupled to an electromagnetic reservoir characterized by noise at finite temperature, where a full quantum description of the environment with noise (with ) is presented. The exact master equation and the associated non-equilibrium Greens functions are solved exactly for such an open system. We show a clear signal of non-Markovian dynamics induced purely by noise. Our analysis is also applicable to other nano/micro mechanical oscillators. Finally, we demonstrate the non-Markovian decoherence dynamics of photon number superposition states using Wigner distribution that could be measured in experiments.
