Nonequilibrium thermometry via an ensemble of initially correlated qubits
Enrico Trombetti, Marco Malitesta, Marco Pezzutto +1
We investigate a nonequilibrium quantum thermometry protocol in which an ensemble of qubits, acting as temperature probes, is weakly coupled to a macroscopic thermal bath. The temp…

Squeezing-enhanced accurate differential sensing under large phase noise
Robin Corgier, Marco Malitesta, Leonid A. Sidorenkov +6
Atom interferometers are reaching sensitivities fundamentally constrained by quantum fluctuations. A main challenge is to integrate entanglement into quantum sensing protocols to e…
