Self-adjointness in Quantum Mechanics: a pedagogical path
Andrea Cintio, Alessandro Michelangeli
Observables in quantum mechanics are represented by self-adjoint operators on Hilbert space. Such ubiquitous, well-known, and very foundational fact, however, is traditionally subt…
Stability of quantum eigenstates and kinetics of wave function collapse in a fluctuating environment
Simone Chiarelli, Piero Chiarelli
The work analyzes the stability of the quantum eigenstates when they are submitted to fluctuations by using the stochastic generalization of the Madelung quantum hydrodynamic appro…
Experimental Lower Bounds to the Classical Capacity of Quantum Channels
Mario A. Ciampini, Álvaro Cuevas, Paolo Mataloni +2
We show an experimental procedure to certify the classical capacity for noisy qubit channels. The method makes use of a fixed bipartite entangled state, where the system qubit is s…
Robust calibration of multiparameter sensors via machine learning at the single-photon level
Valeria Cimini, Emanuele Polino, Mauro Valeri +7
Calibration of sensors is a fundamental step to validate their operation. This can be a demanding task, as it relies on acquiring a detailed modelling of the device, aggravated by…
Engineering multipartite entangled states in doubly pumped parametric down-conversion processes
Alessandra Gatti, Enrico Brambilla, Ottavia Jedrkiewicz
We investigate the quantum state generated by optical parametric down-conversion in a medium driven by two noncollinear light modes. The analysis shows the emergence of…
Two-photon-interaction effects in the bad-cavity limit
Nicolò Piccione, Simone Felicetti, Bruno Bellomo
Various experimental platforms have proven to be valid testbeds for the implementation of nondipolar light-matter interactions, where atomic systems and confined modes interact via…
