Entangling oscillators through environment noise
F Benatti, R Floreanini · Journal of Physics A Mathematical and General · 2006
We consider two independent bosonic oscillators immersed in a common bath, evolving in time with a completely positive, Markovian, quasi-free (Gaussian) reduced dynamics. We show that an initially separated Gaussian state can become entangled as a result of a purely noisy mechanism. In certain cases, the dissipative dynamics allows the persistence of these bath induced quantum correlations even in the asymptotic equilibrium state.
