Quantum Shared Broadcasting
V. Giovannetti, A. S. Holevo
A generalization of quantum broadcasting protocol is presented. Here the goal is to copy an unknown input state into two subsystems which partially overlap. We show that the possib…
Mediated Homogenization
Daniel Burgarth, Vittorio Giovannetti
Homogenization protocols model the quantum mechanical evolution of a system to a fixed state independently from its initial configuration by repeatedly coupling it with a collectio…
Qubit quantum channels: A characteristic function approach
Filippo Caruso, Vittorio Giovannetti
A characterization of qubit quantum channels is introduced. In analogy to what happens in the context of Bosonic channels we exploit the possibility of representing the states of t…
Robust and efficient generator of almost maximal multipartite entanglement
Davide Rossini, Giuliano Benenti
Quantum chaotic maps can efficiently generate pseudo-random states carrying almost maximal multipartite entanglement, as characterized by the probability distribution of bipartite…
Simulation of time evolution with the MERA
Matteo Rizzi, Simone Montangero, Guifre' Vidal
We describe an algorithm to simulate time evolution using the Multi-scale Entanglement Renormalization Ansatz (MERA) and test it by studying a critical Ising chain with periodic bo…
Mott-insulating and glassy phases of polaritons in 1D arrays of coupled cavities
Davide Rossini, Rosario Fazio
By means of analytical and numerical methods we analyze the phase diagram of polaritons in one-dimensional coupled cavities. We locate the phase boundary, discuss the behavior of t…
