Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

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 …

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 …

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 …

In this brief review, we report some new development in the functional determinant approach
(FDA), an exact numerical method, in the studies of a heavy quantum impurity immersed in …

Accurate measurement at low temperatures is essential for both gaining a fundamental
understanding of physical processes and developing technological applications. In this …

We propose experimentally feasible means for nondestructive thermometry of
homogeneous Bose-Einstein condensates in different spatial dimensions (d∈{1, 2, 3}). Our …

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 …
