Exotic States in the Dynamical Casimir Effect
Giuliano Benenti, Stefano Siccardi, Giuliano Strini
We consider the interaction of a qubit with a single mode of the quantized electromagnetic field and show that, in the ultrastrong coupling regime and when the qubit-field interact…
Maximally incompatible quantum observables
Teiko Heinosaari, Jussi Schultz, Alessandro Toigo +1
The existence of maximally incompatible quantum observables in the sense of a minimal joint measurability region is investigated. Employing the universal quantum cloning device it…
Translationally invariant conservation laws of local Lindblad equations
Marko Znidaric, Giuliano Benenti, Giulio Casati
We study the conditions under which one can conserve local translationally invariant operators by local translationally invariant Lindblad equations in one-dimensional rings of spi…
Complexity and instability of quantum motion near a quantum phase transition
Pinquan Qin, Wen-ge Wang, Giuliano Benenti +1
We show that the number of harmonics of the Wigner function, recently proposed as a measure of quantum complexity, can be also used to characterize quantum phase transitions. The n…
Classical and quantum capacities of a fully correlated amplitude damping channel
A. D'Arrigo, G. Benenti, G. Falci +1
We study information transmission over a fully correlated amplitude damping channel acting on two qubits. We derive the single-shot classical channel capacity and show that entangl…
Stochastic Schrödinger Equations for Markovian and non-Markovian cases
I. Semina, V. Semin, F. Petruccione +1
Firstly, the Markovian stochastic Schrödinger equations are presented, together with their connections with the theory of measurements in continuous time. Moreover, the stochastic…
Tasks and premises in quantum state determination
Claudio Carmeli, Teiko Heinosaari, Jussi Schultz +1
The purpose of quantum tomography is to determine an unknown quantum state from measurement outcome statistics. There are two obvious ways to generalize this setting. First, our ta…
Homodyne detection as a near-optimum receiver for phase-shift keyed binary communication in the presence of phase diffusion
Stefano Olivares, Simone Cialdi, Fabrizio Castelli +1
We address binary optical communication channels based on phase-shift keyed coherent signals in the presence of phase diffusion. We prove theoretically and demonstrate experimental…
On a Time-Space Operator (and other Non-Selfadjoint Operators) for Observables in QM and QFT
Erasmo Recami, Michel Zamboni-Rached, Ignazio Licata
Aim of this paper is trying to show the possible significance, and usefulness, of various non-selfadjoint operators for suitable Observables in non-relativistic and relativistic qu…
Non-perturbative interpretation of the Bloch vector's path beyond rotating wave approximation
Giuliano Benenti, Stefano Siccardi, Giuliano Strini
The Bloch vector's path of a two-level system exposed to a monochromatic field exhibits, in the regime of strong coupling, complex corkscrew trajectories. By considering the infini…
Interaction-induced correlations and non-Markovianity of quantum dynamics
Andrea Smirne, Laura Mazzola, Mauro Paternostro +1
We investigate the conditions under which the trace distance between two different states of a given open system increases in time due to the interaction with an environment, there…
Quantum probes to assess correlations in a composite system
Andrea Smirne, Simone Cialdi, Giorgio Anelli +2
We suggest and demonstrate experimentally a strategy to obtain relevant information about a composite system by only performing measurements on a small and easily accessible part o…
Non-Markovian master equations from piecewise dynamics
Bassano Vacchini
We construct a large class of completely positive and trace preserving non-Markovian dynamical maps for an open quantum system. These maps arise from a piecewise dynamics character…
Quantum continuous measurements: The stochastic Schroedinger equations and the spectrum of the output
Alberto Barchielli, Matteo Gregoratti
The stochastic Schrödinger equation, of classical or quantum type, allows to describe open quantum systems under measurement in continuous time. In this paper we review the link be…
