QUANTUMNESS OF CORRELATIONS AND ENTANGLEMENT [PDF]
International Journal of Quantum Information, 2011 Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correlations in a more general perspective. This is done by employing linear maps associated with generalized projective measurements.

Entanglement dynamics in hybrid quantum circuits [PDF]
, 2021 The central philosophy of statistical mechanics (stat-mech) and random-matrix theory of complex systems is that while individual instances are essentially intractable to simulate, the statistical properties of random ensembles obey simple universal"laws".

Entanglement dynamics in chaotic systems [PDF]
, 2004 We study quantum chaos for systems with more than one degree of freedom, for which we present an analysis of the dynamics of entanglement. Our analysis explains the main features of entanglement dynamics and identifies entanglement-based signatures of ...

Computing quantum discord is NP-complete
, 2014 We study the computational complexity of quantum discord (a measure of quantum correlation beyond entanglement), and prove that computing quantum discord is NP-complete.

Detecting quantum entanglement
Theoretical Computer Science, 2002 We review the criteria for separability and quantum entanglement, both in a bipartite as well as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entropic inequalities, bound entanglement and several features of multipartite entanglement.

On the Stochastic Analysis of a Quantum Entanglement Distribution Switch [PDF]
IEEE Transactions on Quantum Engineering, 2019 In this article, we study a quantum entanglement distribution switch that serves $k$ users in a star topology. We model variants of the system as continuous-time Markov chains and obtain expressions for switch capacity, expected number of qubits stored ...

Entanglement in quantum catastrophes [PDF]
Physical Review A, 2005 We classify entanglement singularities for various two-mode bosonic systems in terms of catastrophe theory. Employing an abstract phase-space representation, we obtain exact results in limiting cases for the entropy in cusp, butterfly, and two-dimensional catastrophes.
