Multiparameter squeezing for optimal quantum enhancements in sensor networks
Manuel Gessner, Augusto Smerzi, Luca Pezzè
Squeezing currently represents the leading strategy for quantum enhanced precision measurements of a single parameter in a variety of continuous- and discrete-variable settings and…
Adiabatic Sensing Enhanced by Quantum Criticality
Luca Pezzè, Andreas Trenkwalder, Marco Fattori
We propose an optimal method exploiting second order quantum phase transitions to perform high precision measurements of the control parameter at criticality. Our approach accesses…
Detection of Bell correlations at finite temperature from matter-wave interference fringes
A. Niezgoda, J. Chwedenczuk, L. Pezze +1
We show that matter-wave interference fringes formed by two overlapping atomic clouds can yield information about the non-local Bell correlations. To this end, we consider a simple…
