Modular Many-Body Quantum Sensors
Chiranjib Mukhopadhyay, Abolfazl Bayat
Quantum many-body systems undergoing phase transitions have been proposed as probes enabling beyond-classical enhancement of sensing precision. However, this enhancement is usually…
Multiparameter critical quantum metrology with impurity probes
George Mihailescu, Abolfazl Bayat, Steve Campbell +1
Quantum systems can be used as probes in the context of metrology for enhanced parameter estimation. In particular, the delicacy of critical systems to perturbations can make them…
Critical non-Hermitian topology induced quantum sensing
Saubhik Sarkar, Francesco Ciccarello, Angelo Carollo +1
Non-Hermitian physics predicts open quantum system dynamics with unique topological features such as exceptional points and the non-Hermitian skin effect. We show that this new par…
Quantum metrology with boundary time crystals
V. Montenegro, M. G. Genoni, A. Bayat +1
Quantum sensing is one of the arenas that exemplifies the superiority of quantum technologies over their classical counterparts. Such superiority, however, can be diminished due to…
