Analytic Expression of Quantum Discords in Werner States under LQCC
Entropy, 2020 In this paper, quantum discords in a special kind of states, i.e., Werner states by local quantum operations and classical communication (LQCC) protocols (WLQCC states), are studied.

Simultaneous sudden change in the exact values of geometric quantum discord and measurement induced nonlocality [PDF]
Iranian Journal of Astronomy and Astrophysics, 2018 Recent studies show that two completely distinct fields as quantum information and string theory realization can be related and share some of the same properties.

Hierarchy of efficiently computable and faithful lower bounds to quantum discord [PDF]
, 2015 Quantum discord expresses a fundamental non-classicality of correlations more general than quantum entanglement. We combine the no-local-broadcasting theorem, semidefinite-programming characterizations of quantum fidelity and quantum separability, and a ...

Computing quantum discord is NP-complete
New Journal of Physics, 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.

Robustness of quantum discord to sudden death [PDF]
, 2009 We calculate the dissipative dynamics of two-qubit quantum discord under Markovian environments. We analyze various dissipative channels such as dephasing, depolarizing, and generalized amplitude damping, assuming independent perturbation, in which each ...

Effects of phase shift on bipartite and multipartite correlations of a spin chain under dephasing
Open Physics, 2015 We investigate the effects of phase shift on entanglement, quantum discord, geometric discord, and spinsqueezing of a Heisenberg chain under dephasing. An analytical solution of the present model is obtained.

European Journal of Personality, EarlyView., 2020 Abstract Vocational interests are traditionally conceived as stable preferences for different activities. However, recent theorizing suggests their intraindividual variability. This preregistered experience sampling study examined intraindividual variation in selected vocational interests states and related situation and person factors (N = 237 ...

One-way Unlocalizable Information Deficit
, 2013 We introduce one-way unlocalizable information deficit with respect to the one-way information deficit, similar to the definition of one-way unlocalizable quantum discord with respect to one-way quantum discord.

Quantum discord and entanglement in grover search algorithm
Open Physics, 2016 Imperfections and noise in realistic quantum computers may seriously affect the accuracy of quantum algorithms. In this article we explore the impact of static imperfections on quantum entanglement as well as non-entangled quantum correlations in Grover ...
