Regression of Concurrence via Local Unitary Invariants [PDF]
EntropyConcurrence is a crucial entanglement measure in quantum theory used to describe the degree of entanglement between two or more qubits. Local unitary (LU) invariants can be employed to describe the relevant properties of quantum states.

Bounds for multipartite concurrence
Reports on Mathematical Physics, 2010 We study the entanglement of a multipartite quantum state. An inequality between the bipartite concurrence and the multipartite concurrence is obtained. More effective lower and upper bounds of the multipartite concurrence are obtained.

Lower bound of concurrence for qubit systems
Quantum Information Processing, 2013 We study the concurrence of four-qubit quantum states and provide analytical lower bounds of concurrence in terms of the monogamy inequality of concurrence for qubit systems. It is shown that these lower bounds are able to improve the existing bounds and

W-Class States—Identification and Quantification of Bell-CHSH Inequalities’ Violation [PDF]
EntropyWe discuss a family of W-class states describing three-qubit systems. For such systems, we analyze the relations between the entanglement measures and the nonlocality parameter for a two-mode mixed state related to the two-qubit subsystem.

L’Adriatique, golfe de Venise? Commerce, ports et relations à la fin du Moyen Âge
Anales de la Universidad de Alicante. Historia Medieval, 2022 Aux xive et xve siècles, Venise, placée favorablement en Méditerranée, à proximité des grands fleuves et de cols alpins qui conduisent en Lombardie ou en Allemagne et en Flandre, tente d’imposer un monopole de navigation et de commerce à la mer ...

Case Report: The First Reported Concurrence of Wilson Disease and Bilateral Retinitis Pigmentosa
Frontiers in Medicine, 2022 BackgroundWilson disease (WD) and retinitis pigmentosa (RP) are common genetic disorders in clinical practice, however, the concurrence of WD and RP has never been reported before.

Tavis–Cummings Model with Moving Atoms
Entropy, 2021 In this work, we examine a nonlinear version of the Tavis–Cummings model for two two-level atoms interacting with a single-mode field within a cavity in the context of power-law potentials.

Entanglement of two dipole-couples qubits induced by a thermal field of a cavity with Kerr medium
Физика волновых процессов и радиотехнические системы, 2021 In the present work, we investigated the dynamics of two identical superconducting qubits interacting with the mode of the quantum electromagnetic field of a microwave coplanar cavity with a Kerr medium in the presence of an effective dipole-dipole ...
