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

The detection of microwave fields at single-photon power levels is a much-sought-after
technology, with practical applications in nanoelectronics and quantum information science …

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 …

Quantum many-body systems undergoing phase transitions have been proposed as probes
enabling beyond-classical enhancement of sensing precision. However, this enhancement …

Cavity-electromechanical systems are extensively used for sensing and controlling the
vibrations of mechanical resonators down to their quantum limit. The nonlinear radiation …

We propose and analyze a driven-dissipative quantum sensor that is continuously
monitored close to a dissipative critical point. The sensor relies on the critical open Rabi …

Quantum Fisher information (QFI) may exhibit the irregular behavior at the critical point of
phase transitions of a physical system and be very sensitive to slight variations of some …

Critical behaviour in phase transitions is a resource for enhanced precision metrology. The
reason is that the function, known as Fisher information, is superextensive at critical points …
