The Step-Harmonic Potential

Luca Rizzi, Oliver F. Piattella, Sergio L. Cacciatori +1

We analyze the behavior of a quantum system described by a one-dimensional asymmetric potential consisting of a step plus a harmonic barrier. We solve the eigenvalue equation by th…

Demonstration of a programmable source of two-photon multiqubit entangled states

Simone Cialdi, Davide Brivio, Matteo G. A. Paris

We suggest and demonstrate a novel source of two-photon multipartite entangled states which exploits the transverse spatial structure of spontaneous parametric downconversion toget…

Stochastic Schrödinger equations with coloured noise

A. Barchielli, C. Pellegrini, F. Petruccione

A natural non-Markovian extension of the theory of white noise quantum trajectories is presented. In order to introduce memory effects in the formalism an Ornstein-Uhlenbeck colour…

Experimental estimation of one-parameter qubit gates in the presence of phase diffusion

D. Brivio, S. Cialdi, S. Vezzoli +4

We address estimation of one-parameter qubit gates in the presence of phase diffusion. We evaluate the ultimate quantum limits to precision, seek for optimal probes and measurement…

Thermalization and ergodicity in many-body open quantum systems

Marko Znidaric, Tomaz Prosen, Giuliano Benenti +2

We study thermalization in many-body quantum systems locally coupled to an external bath. It is shown that quantum chaotic systems do thermalize, that is, they exhibit relaxation t…

Towards a more fundamental theory beyond quantum mechanics, avoiding the Schroedinger paradox

Francesco Caravaglios

The main distinction between classical mechanics and quantum mechanics is the lack in the latter of a full mechanical determinism: different final states can arise from the same ph…

Quantum mechanics in phase space: First order comparison between the Wigner and the Fermi function

G. Benenti, G. Strini

The Fermi g_F(x,p) function provides a phase space description of quantum mechanics conceptually different from that based on the the Wigner function W(x,p). In this paper, we show…

A simple representation of quantum process tomography

Giuliano Benenti, Giuliano Strini

We show that the Fano representation leads to a particularly simple and appealing form of the quantum process tomography matrix , in that the matrix is real, the n…

Quantum linear Boltzmann equation

Bassano Vacchini, Klaus Hornberger

We review the quantum version of the linear Boltzmann equation, which describes in a non-perturbative fashion, by means of scattering theory, how the quantum motion of a single tes…

On non-selfadjoint operators for observables in quantum mechanics and quantum field theory

Erasmo Recami, Vladislav S. Olkhovsky, Sergei P. Maydanyuk

Aim of this paper is to show the possible significance, and usefulness, of various non-selfadjoint operators for suitable Observables in non relativistic and relativistic quantum m…

Enhancement of transmission rates in quantum memory channels with damping

G. Benenti, A. D'Arrigo, G. Falci

We consider the transfer of quantum information down a single-mode quantum transmission line. Such quantum channel is modeled as a damped harmonic oscillator, the interaction betwe…

Structure of completely positive quantum master equations with memory kernel

Heinz-Peter Breuer, Bassano Vacchini

Semi-Markov processes represent a well known and widely used class of random processes in classical probability theory. Here, we develop an extension of this type of non-Markovian…
