Pure Gaussian quantum states from passive Hamiltonians and an active local dissipative process (1608.02698v1)

Abstract: We investigate the problem of preparing a pure Gaussian state via reservoir engineering. In particular, we consider a linear quantum system with a passive Hamiltonian and with a single reservoir which acts only on a single site of the system. We then give a full parametrization of the pure Gaussian states that can be prepared by this type of quantum system.
