Distillation of Bell States in Open Systems

چکیده
In this work we review the entire classification of 2 × 2 distillable states for protocols with a finite numbers of copies. We show a distillation protocol that allows to distill Bell states with non zero probability at any time for an initial singlet in vacuum. It is shown that the same protocol used in non zero thermal baths yields a considerable recovering of entanglement.

In this review, we introduce well-known Bell inequalities, the relations between the Bell inequality and quantum separability, and the entangle-ment distillation of quantum states. It is shown that any pure entangled quantum state violates one of Bell-like inequalities. Moreover, quantum states that violate any one of these Bell-like inequalities are shown to be distillable. New Bell inequaliti...
متن کاملBell Inequalities and Entanglement Witnesses Using Two-Body Correlations
It has been shown that there exist Bell inequalities constructed from symmetric oneand two-body correlations that are violated by certain quantum states involving any number of particles. However, the properties of such Bell inequalities have not been completely characterised. In this study, we determine the behaviour of various classes of entangled states with respect to these inequalities. It...

We present a set of Bell inequalities which are sufficient and necessary for separability of general pure multipartite quantum states in arbitrary dimensions. The relations between Bell inequalities and distillability are also studied. We show that any quantum states that violate one of these Bell inequalities are distillable.
متن کاملDistillation protocols: output entanglement and local mutual information.
A complementary behavior between local mutual information and average output entanglement is derived for arbitrary bipartite ensembles. This leads to bounds on the yield of entanglement in distillation protocols that involve disinguishing. This bound is saturated in the hashing protocol for distillation, for Bell-diagonal states.
متن کاملThe equivalence of two approaches to the design of entanglement distillation protocols
We show the equivalence of two approaches to the design of entanglement distillation protocols. The first approach is based on local unitary operations that yield permutations of tensor products of Bell states. The second approach is based on stabilizer codes.
