The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

Present protocols of criticality-enhanced sensing with open quantum sensors assume direct
measurement of the sensor and omit the radiation quanta emitted to the environment …

Quantum batteries are energy storage devices built using quantum mechanical objects,
which are developed with the aim of outperforming their classical counterparts. Proposing …

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 …

Critical quantum systems are a promising resource for quantum metrology applications, due
to the diverging susceptibility developed in proximity of phase transitions. Here, we assess …

The quantum Rabi model (QRM) with linear coupling between light mode and qubit exhibits
the analog of a second-order phase transition for vanishing mode frequency which allows …

Phase transitions represent a compelling tool for classical and quantum sensing
applications. It has been demonstrated that quantum sensors can in principle saturate the …

Quantum thermometry exploits the high level of control in coherent devices to offer
enhanced precision for temperature estimation. This highlights the need for constructing …

We compare critical quantum sensing to passive quantum strategies to perform frequency
estimation, in the case of single-mode quadratic Hamiltonians. We show that, while in the …

We show that the delocalization-localization transition in quantum many-body (QMB)
systems are a compelling quantum resource for achieving quantum-enhanced sensitivity in …
