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 ...

Quantum discord and Maxwell’s demons [PDF]
Physical Review A, 2003 Quantum discord was proposed as an information theoretic measure of the ``quantumness'' of correlations. I show that discord determines the difference between the efficiency of quantum and classical Maxwell's demons in extracting work from collections of correlated quantum systems.

Dynamics of quantum discord of two coupled spin-1/2’s subjected to time-dependent magnetic fields
Results in Physics, 2019 We describe the dynamics of quantum discord of two interacting spin-1/2’s subjected to controllable time-dependent magnetic fields. The exact time evolution of discord is given for various input mixed states consisting of classical mixtures of two Bell ...

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

Angewandte Chemie, EarlyView.By combining gas‐phase rotational spectroscopy and quantum chemistry calculations, we explore how a prototype molecular photoswitch is affected by microhydration. This study unveils the theory‐breaking structural features of camphorquinone oxime, the concerted dynamics of the surrounding water network, and how the oxime subunit actively steers the ...

Exact dynamics of quantum correlations of two qubits coupled to bosonic baths
New Journal of Physics, 2013 Dynamics of the quantum entanglement and quantum discord of two qubits in two independent baths and a common bath with the Lorentzian spectrum are studied exactly in the numerical sense within the hierarchy approach.

Quantum correlation in three-qubit Heisenberg model with Dzyaloshinskii-Moriya interaction
, 2011 We investigate the pairwise thermal quantum discord in a three-qubit XXZ model with Dzyaloshinskii-Moriya (DM) interaction. We find that the DM interaction can increase quantum discord to a fixed value in the anti- ferromagnetic system, but decreases ...
