Abstract

We present the experimental control of Non-Markovian dynamics of open quantum systems simulated with photonic entities. The polarization of light is used as the system, whereas the surrounding environment is represented by light's spatial structure. The control of the dynamics is achieved by the engineering of the environment via spatial interference. Using the behavior of the trace distance, we are able to identify each dynamics and characterize the position of maximum revival of information.
