Concurrence in collective models
We review the entanglement properties in collective models and their relationship with quantum phase transitions. Focusing on the concurrence, which characterizes the two-spin entanglement, we show that for first-order transitions, this quantity is singular but continuous at the transition point, contrary to the common belief. We also propose a conjecture for the concurrence of arbitrary symmet...
متن کاملConcurrence in arbitrary dimensions
Entanglement plays central role in quantum information theory [1]. Pure state entanglement of bipartite systems is well understood in the sense that the relevant parameters for its optimal manipulation by local operations and classical communication (LOCC) have been identified and analyzed [2], [3]. Many efforts have also been devoted to the study of mixed-state entanglement. There, several pos...
متن کاملConcurrence for multipartite states
We construct a generalized concurrence for general multipartite states based on local W-class and GHZ-class operators. We explicitly construct the corresponding concurrence for three-partite states. The construction of the concurrence is interesting since it is based on local operators.

Attached to this letter, please find an insolation sensitivity study of the HI-STORM EHT thermal model for PFS. We trust that the above information fulfills the verbal commitment made by us in an earlier telecon.
متن کاملEstimating Concurrence via Entanglement Witnesses
The interest on quantum entanglement has dramatically increased during the last two decades due to the emerging field of quantum information theory [1, 2]. It turns out that quantum entanglement may be used as basic resources in quantum information processing and communication. The prominent examples are quantum cryptography, quantum teleportation, quantum error correction codes and quantum com...
