Sudden Decoherence Transitions for Quantum Discord [PDF]
, 2014 We investigate the disappearance of discord in 2- and multi-qubit systems subject to decohering influences. We formulate the computation of quantum discord in terms of the generalized Bloch vector, which gives useful insights on the time evolution of ...

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.

Entanglement Distribution and Quantum Discord [PDF]
, 2017 Establishing entanglement between distant parties is one of the most important problems of quantum technology, since long-distance entanglement is an essential part of such fundamental tasks as quantum cryptography or quantum teleportation. In this lecture we review basic properties of entanglement and quantum discord, and discuss recent results on ...

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.

Quantum Discord for Generalized Bloch Sphere States [PDF]
, 2013 In this study for particular states of bipartite quantum system in 2n?2m dimensional Hilbert space state, similar to m or n-qubit density matrices represented in Bloch sphere we call them generalized Bloch sphere states(GBSS), we give an efficient ...

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 ...

Correlations in quantum states and the local creation of quantum discord
, 2012 Quantum discord is usually referred to as a measure for quantum correlations. In the search of the fundamental resource to gain a quantum advantage in quantum information applications, quantum discord is considered a promising candidate. In this paper we
