Joint estimation of phase and uncorrelated dephasing in a differential quantum interferometer
Luca Pezzè, Andrea Santoni, Chiara Mazzinghi +2
Precise measurements in optical and atomic systems often rely on differential interferometry. This method allows to handle large and correlated phase noise contributions -- such as…
Advances in multiparameter quantum sensing and metrology
Luca Pezzè, Augusto Smerzi
Recent years have witnessed a growing interest in understating the limitations imposed by quantum noise in precision measurements and devising techniques to reduce it. The attentio…
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…
Quantum Chaos, Randomness and Universal Scaling of Entanglement in Various Krylov Spaces
Hai-Long Shi, Augusto Smerzi, Luca Pezzè
Multipartite entanglement is a crucial resource for advancing quantum technologies, with considerable research efforts directed toward achieving its rapid and scalable generation.…
Distributed quantum multiparameter estimation with optimal local measurements
Luca Pezzè, Augusto Smerzi
We study the multiparameter sensitivity bounds of a sensor made by an array of spatially-distributed Mach-Zehnder interferometers (MZIs). A generic single non-classical state i…
Metrological usefulness of entanglement and nonlinear Hamiltonians
Satoya Imai, Augusto Smerzi, Luca Pezzè
A central task in quantum metrology is to exploit quantum correlations to outperform classical sensitivity limits. Metrologically useful entanglement is identified when the quantum…
