Diagnostics of quantum-gate coherences via end-point-measurement statistics
Ilaria Gianani, Alessio Belenchia, Stefano Gherardini +3
Quantum coherence is a central ingredient in quantum physics with several theoretical and technological ramifications. In this work we consider a figure of merit encoding the infor…
Projective measurements can probe non-classical work extraction and time-correlations
Santiago Hernández-Gómez, Stefano Gherardini, Alessio Belenchia +3
We demonstrate an experimental technique to characterize genuinely nonclassical multi-time correlations using projective measurements with no ancillae. We implement the scheme in a…
Kirkwood-Dirac quasiprobability approach to the statistics of incompatible observables
Matteo Lostaglio, Alessio Belenchia, Amikam Levy +3
Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability (KDQ) as a tool to properly account for non-classical features in the context of condensed m…
Linear-response approach to critical quantum many-body systems
Ricardo Puebla, Alessio Belenchia, Giulio Gasbarri +2
The characterization of quantum critical phenomena is pivotal for the understanding and harnessing of quantum many-body physics. However, their complexity makes the inference of su…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
