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 …

Nonclassical light and metrological power: An introductory review

KC Tan, H Jeong - AVS Quantum Science, 2019 - pubs.aip.org
In this review, the authors introduce the notion of quantum nonclassicality of light and the
role of nonclassicality in optical quantum metrology. The first part of this paper focuses on …

The role of quantum coherence in non-equilibrium entropy production

JP Santos, LC Céleri, GT Landi… - npj Quantum Information, 2019 - nature.com
Thermodynamic irreversibility is well characterized by the entropy production arising from
non-equilibrium quantum processes. We show that the entropy production of a quantum …

Long-time protection of thermal correlations in a hybrid-spin system under random telegraph noise

F Benabdallah, AU Rahman, S Haddadi, M Daoud - Physical Review E, 2022 - APS
The engineering features of transmitting mediums and their impact on different
characteristics of a quantum system play a significant role in the efficient performance of …

Steered quantum coherence as a signature of quantum phase transitions in spin chains

ML Hu, YY Gao, H Fan - Physical Review A, 2020 - APS
We propose to use the steered quantum coherence (SQC) as a signature of quantum phase
transitions (QPTs). By considering various spin chain models, including the transverse-field …

Directly measuring the degree of quantum coherence using interference fringes

YT Wang, JS Tang, ZY Wei, S Yu, ZJ Ke, XY Xu, CF Li… - Physical Review Letters, 2017 - APS
Quantum coherence is the most distinguished feature of quantum mechanics. It lies at the
heart of the quantum-information technologies as the fundamental resource and is also …

Nonlocal advantage of quantum coherence in a dephasing channel with memory

ML Hu, YH Zhang, H Fan - Chinese Physics B, 2021 - iopscience.iop.org
We investigate nonlocal advantage of quantum coherence (NAQC) in a correlated
dephasing channel modeled by the multimode bosonic reservoir. We obtain analytically the …

Engineering a heat engine purely driven by quantum coherence

S Aimet, H Kwon - Physical Review A, 2023 - APS
The question of whether quantum coherence is a resource beneficial or detrimental to the
performance of quantum heat engines has been thoroughly studied but remains undecided …

Fisher information universally identifies quantum resources

KC Tan, V Narasimhachar, B Regula - Physical Review Letters, 2021 - APS
We show that both the classical as well as the quantum definitions of the Fisher information
faithfully identify resourceful quantum states in general quantum resource theories, in the …

Quantifying the coherence between coherent states

KC Tan, T Volkoff, H Kwon, H Jeong - Physical review letters, 2017 - APS
In this Letter, we detail an orthogonalization procedure that allows for the quantification of
the amount of coherence present in an arbitrary superposition of coherent states. The …
