Classical to quantum in large number limit
Kavan Modi, Rosario Fazio, Saverio Pascazio +2
We construct a quantumness witness following the work of Alicki and van Ryn (AvR) in "A simple test of quantumness for a single system" [J. Phys. A: Math. Theor., vol. 41, 062001 (…
Mass spectrum from stochastic Levy-Schroedinger relativistic equations: possible qualitative predictions in QCD
Nicola Cufaro Petroni, Modesto Pusterla
Starting from the relation between the kinetic energy of a free Levy-Schroedinger particle and the logarithmic characteristic of the underlying stochastic process, we show that it…
Entanglement frustration in multimode Gaussian states
Cosmo Lupo, Stefano Mancini, Paolo Facchi +2
Bipartite entanglement between two parties of a composite quantum system can be quantified in terms of the purity of one party and there always exists a pure state of the total sys…
Entanglement-assisted tomography of a quantum target
A. De Pasquale, P. Facchi, V. Giovannetti +1
We study the efficiency of quantum tomographic reconstruction where the system under investigation (quantum target) is indirectly monitored by looking at the state of a quantum pro…
Statistical distribution of the local purity in a large quantum system
A. De Pasquale, P. Facchi, V. Giovannetti +3
The local purity of large many-body quantum systems can be studied by following a statistical mechanical approach based on a random matrix model. Restricting the analysis to the ca…
Greenberger-Horne-Zeilinger states and few-body Hamiltonians
Paolo Facchi, Giuseppe Florio, Saverio Pascazio +1
The generation of Greenberger-Horne-Zeilinger (GHZ) states is a crucial problem in quantum information. We derive general conditions for obtaining GHZ states as eigenstates of a Ha…
Statistical mechanics of the Cluster-Ising model
Pietro Smacchia, Luigi Amico, Paolo Facchi +4
We study a Hamiltonian system describing a three-spin-1/2 cluster-like interaction competing with an Ising-like anti-ferromagnetic interaction. We compute free energy, spin correla…
Further evidence of antibunching of two coherent beams of fermions
M. Iannuzzi, R. Messi, D. Moricciani +4
We describe an experiment confirming the evidence of the antibunching effect on a beam of non interacting thermal neutrons. The comparison between the results recorded with a high…
Quantum phase transition between cluster and antiferromagnetic states
Wonmin Son, Luigi Amico, Rosario Fazio +3
We study a Hamiltonian system describing a three spin-1/2 cluster-like interaction competing with an Ising-like exchange. We show that the ground state in the cluster phase possess…
The observables of a dissipative quantum system
Dariusz Chruściński, Paolo Facchi, Giuseppe Marmo +1
A time-dependent product is introduced between the observables of a dissipative quantum system, that accounts for the effects of dissipation on observables and commutators. In the…
