Abstract

We consider the time evolution of the tripartite three mode Gaussian state which is initially prepared in genuine entangled pure state. The state undergoes parametric amplification and amplitude damping as well as thermal noise. The correlation matrix of the evolved state is studied in the symmetrical case. The separability conditions are given.

The separability of tripartite Gaussian states with amplification and amplitude damping

Xiaoyu Chen

The most general evolution solution of multi-mode continuous variable states is given when it undergoes amplification, amplitude damping and thermal noise. In the case of some kind of initial Gaussian state totally symmetrically interacting with the environment, the conditions for full separability and full entanglement of the final tripartite three-mode Gaussian state are worked out.

The separability of two-mode Gaussian state under amplification and symmetric damping

Xiaoyu Chen, Li-zhen Jiang, Liang-neng Wu

The performances of a two-mode Gaussian state under parametric amplification, symmetric amplitude damping and thermal noise are studied. The time-dependent complex correlation matrix of the state in evolution is given. The separability of the final two-mode Gaussian state is examined under symmetric amplification and asymmetric amplification separately.

Complex amplification and non-symmetric amplitude damping of two-mode Gaussian state

Li-xhen Jiang

The evolution of two-mode Gaussian state under complex amplification, non-symmetric damping and thermal noise is studied. The analytical time dependent solution of the state characteristic function is obtained in some special cases. The separability criterions are given for the final state of weak complex amplification as well as strong complex amplification.

We derive a necessary and sufficient condition for the separability of tripartite three-mode Gaussian states that is easy to check for any such state. We give a classification of the separability properties of those systems and show how to determine for any state to which class it belongs. We show that there exist genuinely tripartite bound entangled states and point out how to construct and prepare such states.

Separability dynamics of two-mode Gaussian states in parametric conversion and amplification

Alexandre V. Dodonov, V. V. Dodonov, Salomon Sylvain Mizrahi

We give a simplified form of Simon's separability criterion for two-mode Gaussian states, showing that for systems whose unitary evolution is governed by arbitrary time-dependent quadratic Hamiltonians, the separability dynamics is completely described in terms of the determinant of the cross-covariance matrix. As concrete examples, we consider the evolution of the 'inverse negativity coefficient' (which gives a quantitative estimation of the 'degree of entanglement') for two initially uncoupled modes (each being in a squeezed thermal state) in the cases of parametric converter, parametric amplifier and for a cavity whose boundary oscillates in resonance with two field modes.

Entanglement properties of a kind of tripatite Gaussian state

Xiaoyu Chen

Multipartite entanglement is quite difficult to deal with. In this paper, I will consider a particular kind of tripartite Gaussian states, which can be produced as the initial pure tripartite states undergo different noise for each party. I will make use of the relative entropy of entanglement to evaluate the entanglement properties of the states based on the fact that the separability of tripartite Gaussian states is well known. In addition, the procedure of calculating the relative entropy between Gaussian states have developed recently. All these make the evaluating the relative entropy of entanglement of tripartite Gaussian states possible.
