Quantum Simulation of Non-Markovian Qubit Dynamics by an All-Optical Setup

We address the experimental implementation of a quantum simulator based on an optical setup. Our device can simulate the dynamical evolution of a qubit undergoing a dephasing process. In particular, we focus on the dynamics arising from the …

The Role of Monitoring Time and Detectors Efficiencies in Time-Continuous Quantum Magnetometry

We consider the estimation of a weak magnetic field B acting on a continuously monitored ensemble of atoms subjected to collective transverse noise. If N atoms are prepared in a coherent spin state and are not continuously monitored, the estimation …
