Interacting many-body systems display enhanced sensitivity close to critical transition points
due to diverging quantum fluctuations. This criticality-based enhancement has been …

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 criticality, as a fascinating quantum phenomenon, may provide significant
advantages for quantum sensing. Here we propose a dynamic framework for quantum …

Physical systems close to a quantum phase transition exhibit a divergent susceptibility,
suggesting that an arbitrarily high precision may be achieved by exploiting quantum critical …

Quantum sensing is one of the arenas that exemplifies the superiority of quantum
technologies over their classical counterparts. Such superiority, however, can be diminished …

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 investigate critical quantum metrology, that is, the estimation of parameters in many-
body systems close to a quantum critical point, through the lens of Bayesian inference …

Stark systems in which a linear gradient field is applied across a many-body system have
recently been proposed for quantum sensing. Here, we explore sensing capacity of Stark …

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 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 …
