M Mehboudi, A Sanpera… - Journal of Physics A …, 2019 - iopscience.iop.org
Controlling and measuring the temperature in different devices and platforms that operate in
the quantum regime is, without any doubt, essential for any potential application. In this …

Open quantum system dynamics and the mean force Gibbs state

AS Trushechkin, M Merkli, JD Cresser… - AVS Quantum Science, 2022 - pubs.aip.org
The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a
standard assumption across all of the physical sciences. The Gibbs state is determined just …

Estimation of Hamiltonian parameters from thermal states

LP García-Pintos, K Bharti, J Bringewatt, H Dehghani… - Physical Review Letters, 2024 - APS
We upper bound and lower bound the optimal precision with which one can estimate an
unknown Hamiltonian parameter via measurements of Gibbs thermal states with a known …

Weak and ultrastrong coupling limits of the quantum mean force Gibbs state

JD Cresser, J Anders - Physical Review Letters, 2021 - APS
The Gibbs state is widely taken to be the equilibrium state of a system in contact with an
environment at temperature T. However, non-negligible interactions between system and …

Global quantum thermometry

J Rubio, J Anders, LA Correa - Physical review letters, 2021 - APS
A paradigm shift in quantum thermometry is proposed. To date, thermometry has relied on
local estimation, which is useful to reduce statistical fluctuations once the temperature is very …

Work fluctuations in slow processes: quantum signatures and optimal control

HJD Miller, M Scandi, J Anders, M Perarnau-Llobet - Physical review letters, 2019 - APS
An important result in classical stochastic thermodynamics is the work fluctuation-dissipation
relation (FDR), which states that the dissipated work done along a slow process is …

Quantum work statistics close to equilibrium

M Scandi, HJD Miller, J Anders… - Physical Review …, 2020 - APS
We study the statistics of work, dissipation, and entropy production of a quantum quasi-
isothermal process, where the system remains close to thermal equilibrium along the …

Quantum thermometry by single-qubit dephasing

S Razavian, C Benedetti, M Bina… - The European Physical …, 2019 - Springer
We address the dephasing dynamics of a qubit as an effective process to estimate the
temperature of its environment. Our scheme is inherently quantum, since it exploits the …

Nonperturbative renormalization of quantum thermodynamics from weak to strong couplings

WM Huang, WM Zhang - Physical Review Research, 2022 - APS
By solving the exact master equation of open quantum systems, we formulate the quantum
thermodynamics from weak to strong couplings. The open quantum systems exchange …

KV Hovhannisyan, MR Jørgensen, GT Landi… - Prx Quantum, 2021 - APS
Precise thermometry for quantum systems is important to the development of new
technology, and understanding the ultimate limits to precision presents a fundamental …
