Activating optomechanical entanglement
Laura Mazzola, Mauro Paternostro
We propose an optomechanical setup where the activation of entanglement through the pre-availability of non-classical correlations can be demonstrated experimentally. We analyse th…
Experimental Quantum Networking Protocols via Four-Qubit Hyperentangled Dicke States
A. Chiuri, C. Greganti, M. Paternostro +2
We report the experimental demonstration of two quantum networking protocols, namely quantum 1->3 telecloning and open-destination teleportation, implemented using a four-qubit reg…
Using macroscopic entanglement to close the detection loophole in Bell inequality
Youngrong Lim, Mauro Paternostro, Jinhyoung Lee +2
We consider a Bell-like inequality performed using various instances of multi-photon entangled states to demonstrate that losses occurring after the unitary transformations used in…
Formation of helical ion chains
Ramil Nigmatullin, Adolfo del Campo, Gabriele De Chiara +3
We study the nonequilibrium dynamics of the linear to zigzag structural phase transition exhibited by an ion chain confined in a trap with periodic boundary conditions. The transit…
Quantum superpositions of crystalline structures
Jens D. Baltrusch, Cecilia Cormick, Gabriele De Chiara +2
A procedure is discussed for creating coherent superpositions of motional states of ion strings. The motional states are across the structural transition linear-zigzag, and their c…
Non-Markovian effects on non-locality of a qubit-oscillator system
Jie Li, Gerard McKeown, Fernando L. Semiao +1
Non-Markovian evolutions are responsible for a wide variety of physically interesting effects. Here, we study non-locality of the non-classical state of a system consisting of a qu…
Geometric phase kickback in a mesoscopic qubit-oscillator system
G. Vacanti, R. Fazio, M. S. Kim +3
We illustrate a reverse Von Neumann measurement scheme in which a geometric phase induced on a quantum harmonic oscillator is measured using a microscopic qubit as a probe. We show…
Photon production from the vacuum close to the super-radiant transition: When Casimir meets Kibble-Zurek
Giovanni Vacanti, Stefano Pugnetti, Nicolas Didier +4
The dynamical Casimir effect (DCE) predicts the generation of photons from the vacuum due to the parametric amplification of the quantum fluctuation of an electromagnetic field\cit…
The role of environmental correlations in the non-Markovian dynamics of a spin system
Salvatore Lorenzo, Francesco Plastina, Mauro Paternostro
We put forward a framework to study the dynamics of a chain of interacting quantum particles affected by individual or collective multi-mode environment, focussing on the role play…
Entanglement detection in hybrid optomechanical systems
Gabriele De Chiara, Mauro Paternostro, G. Massimo Palma
We study a device formed by a Bose Einstein condensate (BEC) coupled to the field of a cavity with a moving end-mirror and find a working point such that the mirror-light entanglem…
Quantifying, characterizing and controlling information flow in ultracold atomic gases
Pinja Haikka, Suzanne McEndoo, Gabriele de Chiara +2
We study quantum information flow in a model comprising of an impurity qubit immersed in a Bose-Einstein condensed reservoir. We demonstrate how information flux between the qubit…
Bypassing state initialization in Hamiltonian tomography on spin-chains
C. Di Franco, M. Paternostro, M. S. Kim
We provide an extensive discussion on a scheme for Hamiltonian tomography of a spin-chain model that does not require state initialization [Phys. Rev. Lett. 102, 187203 (2009)]. Th…
Extremal Quantum Correlations: Experimental Study with Two-qubit States
Andrea Chiuri, Giuseppe Vallone, Mauro Paternostro +1
We explore experimentally the space of two-qubit quantum correlated mixed states, including frontier ones as defined by the use of quantum discord and von Neumann entropy. Our expe…
Propagation of non-classical correlations across a quantum spin chain
S. Campbell, T. J. G. Apollaro, C. Di Franco +5
We study the transport of quantum correlations across a chain of interacting spin-1/2 particles. As a quantitative figure of merit, we choose a symmetric version of quantum discord…
Orthogonality catastrophe as a consequence of qubit embedding in an ultra-cold Fermi gas
J. Goold, T. Fogarty, N. Lo Gullo +2
We investigate the behaviour of a single qubit coupled to a low-dimensional, ultra-cold Fermi gas. The scattering between the system and the fermions leads to the loss of any coher…
Distributing fully optomechanical quantum correlations
L. Mazzola, M. Paternostro
We present a scheme to prepare quantum correlated states of two mechanical systems based on the pouring of pre-available all-optical entanglement into the state of two micro-mirror…
Bypassing state initialisation in perfect state transfer protocols on spin-chains
C. Di Franco, M. Paternostro, M. S. Kim
Although a complete picture of the full evolution of complex quantum systems would certainly be the most desirable goal, for particular Quantum Information Processing schemes such…
Two proposals for testing quantum contextuality of continuous-variable states
Gerard McKeown, Matteo G. A. Paris, Mauro Paternostro
We investigate the violation of non-contextuality by a class of continuous variable states, including variations of entangled coherent states (ECS's) and a two-mode continuous supe…
Faithful test of non-local realism with entangled coherent states
Chang-Woo Lee, Mauro Paternostro, Hyunseok Jeong
We investigate the violation of Leggett's inequality for non-local realism using entangled coherent states and various types of local measurements. We prove mathematically the rela…
