Colloquium: Quantum coherence as a resource

A Streltsov, G Adesso, MB Plenio - Reviews of Modern Physics, 2017 - APS
The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

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 …

No-go theorem for the characterization of work fluctuations in coherent quantum systems

M Perarnau-Llobet, E Bäumer, KV Hovhannisyan… - Physical review …, 2017 - APS
An open question of fundamental importance in thermodynamics is how to describe the
fluctuations of work for quantum coherent processes. In the standard approach, based on a …

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 …

Resource theory of superposition

T Theurer, N Killoran, D Egloff, MB Plenio - Physical review letters, 2017 - APS
The superposition principle lies at the heart of many nonclassical properties of quantum
mechanics. Motivated by this, we introduce a rigorous resource theory framework for the …

Non-additive dissipation in open quantum networks out of equilibrium

MT Mitchison, MB Plenio - New Journal of Physics, 2018 - iopscience.iop.org
We theoretically study a simple non-equilibrium quantum network whose dynamics can be
expressed and exactly solved in terms of a time-local master equation. Specifically, we …

Using and reusing coherence to realize quantum processes

MG Díaz, K Fang, X Wang, M Rosati, M Skotiniotis… - Quantum, 2018 - quantum-journal.org
Coherent superposition is a key feature of quantum mechanics that underlies the advantage
of quantum technologies over their classical counterparts. Recently, coherence has been …

Relative quantum coherence, incompatibility, and quantum correlations of states

ML Hu, H Fan - Physical Review A, 2017 - APS
Quantum coherence, incompatibility, and quantum correlations are fundamental features of
quantum physics. A unified view of those features is crucial for revealing quantitatively their …

Experimental validation of fully quantum fluctuation theorems using dynamic Bayesian networks

K Micadei, JPS Peterson, AM Souza, RS Sarthour… - Physical Review Letters, 2021 - APS
Fluctuation theorems are fundamental extensions of the second law of thermodynamics for
small systems. Their general validity arbitrarily far from equilibrium makes them invaluable in …

Passivity and practical work extraction using Gaussian operations

EG Brown, N Friis, M Huber - New Journal of Physics, 2016 - iopscience.iop.org
Quantum states that can yield work in a cyclical Hamiltonian process form one of the primary
resources in the context of quantum thermodynamics. Conversely, states whose average …
