Coherent expansion of the motional state of a massive nanoparticle beyond its linear dimensions
R. Muffato, T. S. Georgescu, M. Carlesso +2
Quantum mechanics predicts that massive particles exhibit wave-like behavior. Matterwave interferometry has been able to validate such predictions through ground-breaking experimen…
STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
Criticality-amplified quantum probing of a spontaneous collapse model
Giorgio Zicari, Matteo Carlesso, Andrea Trombettoni +1
Spontaneous collapse models, which are phenomenological mechanisms introduced and designed to account for dynamical wavepacket reduction, are attracting a growing interest from the…
Improved bounds on collapse models from rotational noise of LISA Pathfinder
Davide Giordano Ario Altamura, Andrea Vinante, Matteo Carlesso
Spontaneous wavefunction collapse models offer a solution to the quantum measurement problem, by modifying the Schrödinger equation with nonlinear and stochastic terms. The Contin…
Generation of classical non-Gaussian distributions by squeezing a thermal state into non-linear motion of levitated optomechanics
Rafael Muffato, Tiberius Georgescu, Jack Homans +6
We report on an experiment achieving the dynamical generation of non-Gaussian states of motion of a levitated optomechanical system. We access intrinsic Duffing-like nonlinearities…
Quantifying protocol efficiency: a thermodynamic figure of merit for classical and quantum state-transfer protocols
Qiongyuan Wu, Mario A. Ciampini, Mauro Paternostro +1
Manipulating quantum systems undergoing non-Gaussian dynamics in a fast and accurate manner is becoming fundamental to many quantum applications. Here, we focus on classical and qu…
