Multispin probes for thermometry in the strong-coupling regime

M Brenes, D Segal - Physical Review A, 2023‏ - APS
We study the sensitivity of thermometric probes that are composed of N spins coupled to a
sample prepared at temperature T. Our analysis extends beyond the weak-coupling limit into …

Thermometry of strongly correlated fermionic quantum systems using impurity probes

G Mihailescu, S Campbell, AK Mitchell - Physical Review A, 2023‏ - APS
We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

Non-Markovian enhancement of nonequilibrium quantum thermometry

Y Aiache, C Seida, K El Anouz, A El Allati - Physical Review E, 2024‏ - APS
Accurate measurement at low temperatures is essential for both gaining a fundamental
understanding of physical processes and develo** technological applications. In this …

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 …

Quantum metrology and sensing with many-body systems

V Montenegro, C Mukhopadhyay, R Yousefjani… - arxiv preprint arxiv …, 2024‏ - arxiv.org
The main power of quantum sensors is achieved when the probe is composed of several
particles. In this situation, quantum features such as entanglement contribute in enhancing …

Harnessing coherence generation for precision single-and two-qubit quantum thermometry

Y Aiache, A El Allati, K El Anouz - Physical Review A, 2024‏ - APS
Quantum probes, such as single-and two-qubit probes, can accurately measure the
temperature of a bosonic bath. The current investigation assesses the precision of the …

Optimal probes for global quantum thermometry

WK Mok, K Bharti, LC Kwek, A Bayat - Communications physics, 2021‏ - nature.com
Quantum thermodynamics has emerged as a separate sub-discipline, revising the concepts
and laws of thermodynamics, at the quantum scale. In particular, there has been a disruptive …

Bayesian estimation for collisional thermometry

GO Alves, GT Landi - Physical Review A, 2022‏ - APS
Quantum thermometry exploits the high level of control in coherent devices to offer
enhanced precision for temperature estimation. This highlights the need for constructing …
