Entanglement, one of the important features of quantum systems, which does not exist classically, has been known as a key resource for some quantum computation and information processes. But the entanglement of a system changes due to its unavoidable interactions with environment. To study the entanglement changes, one needs to make use of an entanglement measure in order to specify the entangl...

Xiu-Hong Gao, Shao-Ming Fei, and Ke Wu a Department of Mathematics, Capital Normal University, Beijing 100037, China b Max Planck Institute for Mathematics in the Sciences, D-04103 Leipzig, Germany Abstract We derive an analytical lower bound for the concurrence of tripartite quantum mixed states. A functional relation is established relating concurrence and the generalized partial transpositions.

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...

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.

Extramammary Paget’s disease and vulvar intraepithelial neoplasia are common lesions of vulve, but synchronous occurrence is rare in a same location. Herein we describe a concurrence of primary cutaneous extra mammary Paget’s disease and squamous cell carcinoma in situ of vulva in an Iranian women. A 59 year old woman, initially presented to Kosar teaching hospital gynecology clinic April 2017 ...

For any three-qubit quantum systems ABC, Oliveira et al. numerically found that both the concurrence and the entanglement of formation (EoF) obey the linear monogamy relations in pure states. They also conjectured that the linear monogamy relations can be saturated when the focus qubit A is maximally entangled with the joint qubits BC. In this work, we prove analytically that both the concurren...

The topics of this paper builds on the fact that call-in radio programmes are inherently confrontational and focuses on the manner in which confrontations of opinion relate to the flow of conversation on air. Through the use of conversation, a specific fusion of the private and the public occurs by means of which call-in programmes transform into a specific public forum, where the realms of the...
