Experimental implementation of fully controlled dephasing dynamics and synthetic spectral densities

The study of dephasing dynamics have wide implications for understanding open systems evolutions and in particular decoherence of qubits. Here, the authors implement arbitrary qubit decoherence dynamics in a photonic simulator, also capable of implementing non-positive dynamical maps.
