[HTML][HTML] Exploring quantum thermodynamics with NMR

CHS Vieira, JLD de Oliveira, JFG Santos… - Journal of Magnetic …, 2023 - Elsevier
Quantum thermodynamics seeks to extend non-equilibrium stochastic thermodynamics to
small quantum systems where non-classical features are essential to its description. Such a …

Noisy quantum metrology with the assistance of indefinite causal order

F Chapeau-Blondeau - Physical Review A, 2021 - APS
A generic qubit unitary operator affected by depolarizing noise is duplicated and inserted in
a quantum switch process, realizing a superposition of causal orders. The characterization …

Measurement-based quantum heat engine in a multilevel system

MF Anka, TR de Oliveira, D Jonathan - Physical Review E, 2021 - APS
We compare quantum Otto engines based on two different cycle models: a two-bath model,
with a standard heat source and sink, and a measurement-based protocol, where the role of …

Cooperative isentropic charging of hybrid quantum batteries

YV de Almeida, TFF Santos, MF Santos - Physical Review A, 2023 - APS
Quantum batteries are quantum systems used to store energy to be later extracted by an
external agent in the form of work to perform some task. Here we study the charging of a …

Joint measurability in nonequilibrium quantum thermodynamics

K Beyer, R Uola, K Luoma, WT Strunz - Physical Review E, 2022 - APS
In this Letter we investigate the concept of quantum work and its measurability from the
viewpoint of quantum measurement theory. Very often, quantum work and fluctuation …

All states are universal catalysts in quantum thermodynamics

P Lipka-Bartosik, P Skrzypczyk - Physical Review X, 2021 - APS
Quantum catalysis is a fascinating concept that demonstrates how certain transformations
can only become possible when given access to a specific resource that has to be returned …

Thermodynamic length and work optimization for Gaussian quantum states

M Mehboudi, HJD Miller - Physical Review A, 2022 - APS
Constructing optimal thermodynamic processes in quantum systems relies on managing the
balance between the average excess work and its stochastic fluctuations. Recently it has …

Experimental study of the generalized Jarzynski fluctuation relation using entangled photons

PHS Ribeiro, T Häffner, GL Zanin, NR da Silva… - Physical Review A, 2020 - APS
Optical modes possessing orbital angular momentum constitute a very useful platform for
experimental studies on the quantum limits of thermodynamics. Here, we present …

Magnonic Otto thermal machine

N Vidal-Silva, FJ Peña, RE Troncoso, P Vargas - Physical Review Research, 2024 - APS
We propose a quasistatic magnon-based Otto thermal machine in two-dimensional (2D)
magnetic insulators. The thermodynamical cycles are engineered by exposing a magnon …

Second law of thermodynamics for batteries with vacuum state

P Lipka-Bartosik, P Mazurek, M Horodecki - Quantum, 2021 - quantum-journal.org
In stochastic thermodynamics work is a random variable whose average is bounded by the
change in the free energy of the system. In most treatments, however, the work reservoir that …
