A pure state decoheres into a mixed state as the system entangles with an environment which is initially in a pure state. However, it is not definite that the system becomes entangled with a confined environment with which it only ever interacts. We investigate the disentangling mechanism by considering the quantum correlation between a two-mode squeezed state and a thermal environment.
