Entanglement of Distillation and Conditional Mutual Information
In previous papers, we expressed the Entanglement of Formation in terms of Conditional Mutual Information (CMI). In this brief paper, we express the Entanglement of Distillation in terms of CMI.
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 کاملAn additive and operational entanglement measure: conditional entanglement of mutual information.
Based on the monogamy of entanglement, we develop the technique of quantum conditioning to build an additive entanglement measure: the conditional entanglement of mutual information. Its operational meaning is elaborated to be the minimal net "flow of qubits" in the process of partial state merging. The result and conclusion can also be generalized to multipartite entanglement cases.

متن کاملBranes, Waves and AdS Orbifolds
The embedding of a Taub-NUT space in the directions transverse to the world volume of branes describes branes at (spherical) orbifold singularities. Similarly, the embedding of a pp-wave in the brane world volume yields an AdS orbifold. In case of the D1-D5–brane system, the AdS3 orbifolds yields a BTZ black hole; as we will show, the same holds for D3–branes corresponding to AdS5. In addition ...
