Quantum limit for driven linear non-Markovian open-quantum-systems
New Journal of Physics, 2015 The interplay between non-Markovian dynamics and driving fields in the survival of entanglement between two non-degenerate oscillators is considered here.

New Journal of Physics, 2015 We characterize correlations in polarization and time of photon pairs generated from a cold cloud of ^87 Rb atoms via a four-wave mixing process in a cascade level scheme.

Nonlocal Entanglement Transformations Achievable by Separable Operations [PDF]
, 2008 For manipulations of multipartite quantum systems, it was well known that all local operations assisted by classical communication (LOCC) constitute a proper subset of the class of separable operations.

Dissipative Bose–Einstein condensation in contact with a thermal reservoir
New Journal of Physics, 2016 We investigate the real-time dynamics of open quantum spin-1/2 or hardcore boson systems on a spatial lattice, which are governed by a Markovian quantum master equation.

Directly comparing entanglement-enhancing non-Gaussian operations
New Journal of Physics, 2015 Single-photon-level non-Gaussian operations—photon addition, photon subtraction, and their coherent superposition—are powerful tools with which to increase entanglement in continuous-variable optical states.

Quantum entanglement in coupled harmonic oscillator systems: from micro to macro
New Journal of Physics, 2016 We investigate the entanglement dynamics of several models of coupled harmonic oscillators, whereby a number of properties concerning entanglement have been scrutinized, such as how the environment affects entanglement of a system, and death and revival ...

Characterization process of emission sources of spin entangled pairs with several species
, 2011 Normally, sources of entangled pairs generate several species of them. This work proposes a characterization algorithm for relatively general bipartite entangled states, generating several standard Bell states with controlled population as output.Comment:

Robust quantum correlations in out-of-equilibrium matter–light systems
New Journal of Physics, 2015 High precision macroscopic quantum control in interacting light–matter systems remains a significant goal toward novel information processing and ultra-precise metrology. We show that the out-of-equilibrium behavior of a paradigmatic light–matter system (

Entangled light from Bose-Einstein condensates [PDF]
, 2008 We propose a method to generate entangled light with a Bose-Einstein condensate trapped in a cavity, a system realized in recent experiments. The atoms of the condensate are trapped in a periodic potential generated by a cavity mode.

, 2010 We report on the generation of entangled states of light between the wavelengths 810 and 1550 nm in the continuous variable regime. The fields were produced by type I optical parametric oscillation in a standing-wave cavity build around a periodically ...
