Cooling many particles to very low temperatures
Almut Beige, Peter L. Knight, Giuseppe Vitiello
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The…
Equivalence between Entanglement and the Optimal Fidelity of Continuous Variable Teleportation
Gerardo Adesso, Fabrizio Illuminati
We devise the optimal form of Gaussian resource states enabling continuous variable teleportation with maximal fidelity. We show that a nonclassical optimal fidelity of -user te…
From Fischer projections to quantum mechanics of tetrahedral molecules: new perspectives in chirality
S. Capozziello, A. Lattanzi
The algebraic structure of central molecular chirality can be achieved starting from the geometrical representation of bonds of tetrahedral molecules, as complex numbers in polar f…
Unitarily localizable entanglement of Gaussian states
Alessio Serafini, Gerardo Adesso, Fabrizio Illuminati
We consider generic -mode bipartitions of continuous variable systems, and study the associated bisymmetric multimode Gaussian states. They are defined as -mode G…
Continuous variable tangle, monogamy inequality, and entanglement sharing in Gaussian states of continuous variable systems
Gerardo Adesso, Fabrizio Illuminati
For continuous-variable systems, we introduce a measure of entanglement, the continuous variable tangle ({\em contangle}), with the purpose of quantifying the distributed (shared)…
Path Integral Approach to 't Hooft's Derivation of Quantum from Classical Physics
Massimo Blasone, Petr Jizba, Hagen Kleinert
We present a path-integral formulation of 't Hooft's derivation of quantum from classical physics. The crucial ingredient of this formulation is Gozzi et al.'s supersymmetric path…
Quasideterministic generation of maximally entangled states of two mesoscopic atomic ensembles by adiabatic quantum feedback
Antonio Di Lisi, Silvio De Siena, Fabrizio Illuminati +1
We introduce an efficient, quasideterministic scheme to generate maximally entangled states of two atomic ensembles. The scheme is based on quantum nondemolition measurements of to…
Quantum noise induced entanglement and chaos in the dissipative quantum model of brain
Eliano Pessa, Giuseppe Vitiello
We discuss some features of the dissipative quantum model of brain in the frame of the formalism of quantum dissipation. Such a formalism is based on the doubling of the system deg…
Multiplicativity of maximal output purities of Gaussian channels under Gaussian inputs
A. Serafini, J. Eisert, M. M. Wolf
We address the question of the multiplicativity of the maximal p-norm output purities of bosonic Gaussian channels under Gaussian inputs. We focus on general Gaussian channels resu…
Quantification and scaling of multipartite entanglement in continuous variable systems
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We present a theoretical method to determine the multipartite entanglement between different partitions of multimode, fully or partially symmetric Gaussian states of continuous var…
Quantum Logic and Non-Commutative Geometry
P. A. Marchetti, R. Rubele
We propose a general scheme for the "logic" of elementary propositions of physical systems, encompassing both classical and quantum cases, in the framework given by Non Commutative…
Logarithmic divergence of the block entanglement entropy for the ferromagnetic Heisenberg model
Vladislav Popkov, Mario Salerno
Recent studies have shown that logarithmic divergence of entanglement entropy as function of size of a subsystem is a signature of criticality in quantum models. We demonstrate tha…
Cooling many particles at once
Almut Beige, Peter L. Knight, Giuseppe Vitiello
We propose a mechanism for the collective cooling of a large number N of trapped particles to very low temperatures by applying red-detuned laser fields and coupling them to the qu…
Entropic localization in non-unitary Newtonian gravity
Sergio De Filippo, Filippo Maimone
The localizing properties and the entropy production of the Newtonian limit of a nonunitary version of fourth order gravity are analyzed. It is argued that pure highly unlocalized…
Extremal entanglement and mixedness in continuous variable systems
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We investigate the relationship between mixedness and entanglement for Gaussian states of continuous variable systems. We introduce generalized entropies based on Schatten -norm…
