Quantum coherence and geometric quantum discord

ML Hu, X Hu, J Wang, Y Peng, YR Zhang, H Fan - Physics Reports, 2018 - Elsevier
Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

The classical-quantum boundary for correlations:<? format?> Discord and related measures

K Modi, A Brodutch, H Cable, T Paterek, V Vedral - Reviews of Modern Physics, 2012 - APS
One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Quantum discord and its allies: a review of recent progress

A Bera, T Das, D Sadhukhan, SS Roy… - Reports on Progress …, 2017 - iopscience.iop.org
We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Bell nonlocality, entanglement, and entropic uncertainty in a Heisenberg model under intrinsic decoherence: DM and KSEA interplay effects

M Hashem, ABA Mohamed, S Haddadi, Y Khedif… - Applied Physics B, 2022 - Springer
Bell's inequalities are described by the sums of correlations including non-commuting
observables in each of two systems. Bell's inequalities violation is possible since the …

[HTML][HTML] Intrinsic decoherence effects on nonclassical correlations in a symmetric spin–orbit model

ABA Mohamed, AN Khedr, S Haddadi, AU Rahman… - Results in Physics, 2022 - Elsevier
Nonclassical correlations dynamics of local quantum Fisher information, trace-norm
measurement-induced nonlocality, and log-negativity are investigated in a symmetric spin …

Dynamics of quantum correlations in colored-noise environments

C Benedetti, F Buscemi, P Bordone, MGA Paris - Physical Review A—Atomic …, 2013 - APS
We address the dynamics of entanglement and quantum discord for two noninteracting
qubits initially prepared in a maximally entangled state and then subjected to a classical …

From quantum coherence to quantum correlations

Y Sun, Y Mao, S Luo - Europhysics Letters, 2017 - iopscience.iop.org
In quantum mechanics, quantum coherence of a state relative to a quantum measurement
can be identified with the quantumness that has to be destroyed by the measurement. In …

Dynamics of entropic measurement-induced nonlocality in structured reservoirs

ML Hu, H Fan - Annals of Physics, 2012 - Elsevier
We propose the entropic measurement-induced nonlocality (MIN) as the maximal increment
of von Neumann entropy induced by the locally non-disturbing measurement, and study its …

Protecting quantum Fisher information in correlated quantum channels

ML Hu, HF Wang - Annalen der Physik, 2020 - Wiley Online Library
Quantum Fisher information (QFI) has potential applications in quantum metrology tasks. QFI
is investigated when the consecutive actions of a quantum channel on the sequence of …

Enhancing nonlocal advantage of quantum coherence in correlated quantum channels

YX Xie, ZY Qin - Quantum Information Processing, 2020 - Springer
We explore decay behaviors of the nonlocal advantage of quantum coherence (NAQC) for
two qubits traversing the phase flap, bit flip, bit-phase flip, and depolarizing channels. For …
