We describe the behaviour of the Gaussian quantum in a system of two bosonic modes evolving in a Gaussian noisy channel. The dynamics of the quantum system interacting weakly with a squeezed thermal reservoir is determined in the framework of the axiomatic theory of open quantum systems using quantum dynamical semigroups. We study the quantum steering using the symplectic formalism and we find out that the steerability in the considered open system interacting with a squeezed thermal reservoir is suppressed for all non-zero values of the thermal photon number and squeezing parameter of the reservoir. The Gaussian quantum steerability manifests a sudden suppression like entanglement, namely it decays at a finite moment of time. |
