Breaking quantum linearity: constraints from human perception and cosmological implications
Angelo Bassi, Dirk-Andre' Deckert, Luca Ferialdi
Resolving the tension between quantum superpositions and the uniqueness of the classical world is a major open problem. One possibility, which is extensively explored both theoreti…
On spontaneous photon emission in collapse models
Stephen L. Adler, Angelo Bassi, Sandro Donadi
We reanalyze the problem of spontaneous photon emission in collapse models. We show that the extra term found by Bassi and Duerr is present for non-white (colored) noise, but its c…
Continuous variable quantum key distribution in non-Markovian channels
Ruggero Vasile, Stefano Olivares, Matteo G A Paris +1
We address continuous variable quantum key distribution (QKD) in non-Markovian lossy channels and show how the non-Markovian features may be exploited to enhance security and/or to…
Three qubits in a symmetric environment: dissipatively generated asymptotic entanglement
Fabio Benatti, Adam Nagy
We study the asymptotic entanglement of three identical qubits under the action of a Markovian open system dynamics that does not distinguish them. We show that by adding a complet…
Squeezing Inequalities and Entanglement for Identical Particles
F. Benatti, R. Floreanini, U. Marzolino
By identifying non-local effects in systems of identical Bosonic qubits through correlations of their commuting observables, we show that entanglement is not necessary to violate c…
Reconstruction of time-dependent coefficients: a check of approximation schemes for non-Markovian convolutionless dissipative generators
Bruno Bellomo, Antonella De Pasquale, Giulia Gualdi +1
We propose a procedure to fully reconstruct the time-dependent coefficients of convolutionless non-Markovian dissipative generators via a finite number of experimental measurements…
