Programmable Cavity Squeezing for Distributed Sensing in a Tweezer Array
Youssef Trifa, Marco Fattori, Luca Pezzè
Field sensing with state-of-the-art atom interferometers is restricted to the use of uncorrelated devices op- erating in parallel. We can overcome this limitation by using distribu…
Many-body gravitating quantum systems with Bose-Einstein condensates and dipolar analogue
Youssef Trifa, Dario Cafasso, Marco Fattori +1
Quantum probes of gravity in the Newtonian regime, based on mass-energy equivalence in clocks or spatial superpositions in interferometers, share a common description in terms of a…
Hierarchy of saturation conditions for multiparameter quantum metrology bounds
Satoya Imai, Jing Yang, Luca Pezzè
The quantum Cramér-Rao (QCR) bound sets the ultimate local precision limit for unbiased multiparameter estimation. Unlike in the single-parameter case, however, its saturability is…
A geometric criterion for optimal measurements in multiparameter quantum metrology
Jing Yang, Satoya Imai, Luca Pezzè
Determining when the multiparameter quantum Cramér--Rao bound (QCRB) is saturable with experimentally relevant single-copy measurements is a central open problem in quantum metrolo…
Semi-classical geometric tensor in multiparameter quantum information
Satoya Imai, Jing Yang, Luca Pezzè
The discrepancy between quantum distinguishability in Hilbert space and classical distinguishability in probability space is expressed by the gap between the quantum and classical…
Transport regimes of cold gases in a two-dimensional anisotropic disorder
L. Pezze, M. Robert-de-Saint-Vincent, T. Bourdel +6
We numerically study the dynamics of cold atoms in a two-dimensional disordered potential. We consider an anisotropic speckle potential and focus on the classical regime, which is…
Anisotropic 2D diffusive expansion of ultra-cold atoms in a disordered potential
M. Robert-de-Saint-Vincent, J. -P. Brantut, B. Allard +6
We study the horizontal expansion of vertically confined ultra-cold atoms in the presence of disorder. Vertical confinement allows us to realize a situation with a few coupled harm…
