[HTML][HTML] Charging a quantum battery with linear feedback control

MT Mitchison, J Goold, J Prior - Quantum, 2021 - quantum-journal.org
Energy storage is a basic physical process with many applications. When considering this
task at the quantum scale, it becomes important to optimise the non-equilibrium dynamics of …

Thermodynamic uncertainty relations including measurement and feedback

PP Potts, P Samuelsson - Physical Review E, 2019 - APS
Thermodynamic uncertainty relations quantify how the signal-to-noise ratio of a given
observable is constrained by dissipation. Fluctuation relations generalize the second law of …

Quantum thermodynamically consistent local master equations

A Hewgill, G De Chiara, A Imparato - Physical Review Research, 2021 - APS
Local master equations are a widespread tool to model open quantum systems, especially
in the context of many-body systems. These equations, however, are believed to lead to …

Bounds in nonequilibrium quantum dynamics

Z Gong, R Hamazaki - International Journal of Modern Physics B, 2022 - World Scientific
We review various bounds concerning out-of-equilibrium dynamics in few-level and many-
body quantum systems. We primarily focus on closed quantum systems but will also mention …

Quantum thermodynamics under continuous monitoring: A general framework

G Manzano, R Zambrini - AVS Quantum Science, 2022 - pubs.aip.org
The thermodynamics of quantum systems driven out of equilibrium has attracted increasing
attention in the last decade, in connection with quantum information and statistical physics …

Dynamics of a qubit while simultaneously monitoring its relaxation and dephasing

Q Ficheux, S Jezouin, Z Leghtas, B Huard - Nature communications, 2018 - nature.com
Decoherence originates from the leakage of quantum information into external degrees of
freedom. For a qubit, the two main decoherence channels are relaxation and dephasing …

Heat and work along individual trajectories of a quantum bit

M Naghiloo, D Tan, PM Harrington, JJ Alonso, E Lutz… - Physical review …, 2020 - APS
We use a near quantum limited detector to experimentally track individual quantum state
trajectories of a driven qubit formed by the hybridization of a waveguide cavity and a …

Autonomous conversion of information to work in quantum dots

R Sánchez, P Samuelsson, PP Potts - Physical Review Research, 2019 - APS
We consider an autonomous implementation of Maxwell's demon in a quantum dot
architecture acting on a system without changing its number of particles or its energy. As in …
