Metrological quantum-to-classical crossover in the volume of a noisy quasiperiodic lattice
Priya Ghosh, Debarupa Saha, Ujjwal Sen +1
Localization-delocalization transitions have recently been proposed for building a class of efficient quantum many-body critical sensors. This work scrutinizes metrological perform…
Power-law-graded Ising Interactions Stabilize Time Crystals Realizing Quantum Energy Storage and Sensing
Ayan Sahoo, Debraj Rakshit
We study discrete time-crystalline (DTC) phases in one-dimensional spin-1/2 chains with power-law-graded Ising interactions under periodic Floquet driving. By generalizing Stark lo…
Quantum sensing with ultracold simulators in lattice and ensemble systems: a review
Keshav Das Agarwal, Sayan Mondal, Ayan Sahoo +3
Sensing of parameters is an important aspect in all disciplines, with applications ranging from fundamental science to medicine. Quantum sensing and metrology is an emerging field…
Measurement-Induced Local Dephasing Generates Symmetrically Located Entangled Sites in a Fermionic Tight-Binding Lattice
Aitijhya Saha, Srijani Das, Debraj Rakshit
We investigate an odd-sized fermionic open tight-binding chain subjected to stochastic projective measurements at its central site, effectively inducing localized dephasing. Focusi…
Enhanced sensing of a weak Stark field under the influence of Aubry-André-Harper criticality
Ayan Sahoo, Debraj Rakshit
The localization transition can be exploited as a resource for achieving quantum-enhanced sensitivity in parameter estimation. We demonstrate that by employing different classes of…
Multicritical quantum sensors driven by symmetry-breaking
Sayan Mondal, Ayan Sahoo, Ujjwal Sen +1
Quantum criticality has been demonstrated as a useful quantum resource for parameter estimation. This includes second-order, topological and localization transitions. In all these…
