Sensing microscopic noise events by frequent quantum measurements
Salvatore Virzì, Laura T. Knoll, Alessio Avella +8
We propose and experimentally demonstrate a general method allowing us to unravel microscopic noise events that affect a continuous quantum variable. Such unraveling is achieved by…
Stochastic entropy production: Fluctuation relation and irreversibility mitigation in non-unital quantum dynamics
Eliana Fiorelli, Stefano Gherardini, Stefano Marcantoni
In this work, we study the stochastic entropy production in open quantum systems whose time evolution is described by a class of non-unital quantum maps. In particular, as in [Phys…
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…
Experimental signature of initial quantum coherence on entropy production
S. Hernández-Gómez, S. Gherardini, A. Belenchia +3
We report the experimental quantification of the contribution to non-equilibrium entropy production that stems from the quantum coherence content in the initial state of a qubit ex…
Quantum Annealing for Neural Network optimization problems: a new approach via Tensor Network simulations
Guglielmo Lami, Pietro Torta, Giuseppe E. Santoro +1
Quantum Annealing (QA) is one of the most promising frameworks for quantum optimization. Here, we focus on the problem of minimizing complex classical cost functions associated wit…
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…
