f-oscillators deformation for Moyal algebras
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
Using general construction of star-product the q-deformed Wigner-Weyl-Moyal quantization procedure is elaborated. The q-deformed Groenewold kernel determining the product of quantu…
Hierarchies of Geometric Entanglement
M. Blasone, F. Dell'Anno, S. De Siena +1
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of elementary subsystems, they are defined as the distances from the sets of …
Fully frustrated Josephson junction ladders with Mobius boundary conditions as topologically protected qubits
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
We show how to realize a ``protected'' qubit by using a fully frustrated Josephson Junction ladder (JJL) with Mobius boundary conditions. Such a system has been recently studied wi…
Schwinger Representation for the Symmetric Group: Two explicit constructions for the Carrier Space
S. Chaturvedi, G. Marmo, N. Mukunda +1
We give two explicit construction for the carrier space for the Schwinger representation of the group . While the first relies on a class of functions consisting of monomials…
Quantum Zeno dynamics and quantum Zeno subspaces
Paolo Facchi, Giuseppe Marmo, Saverio Pascazio
A quantum Zeno dynamics can be obtained by means of frequent measurements, frequent unitary kicks or a strong continuous coupling and yields a partition of the total Hilbert space…
A class of inequalities inducing new separability criteria for bipartite quantum systems
Paolo Aniello, Cosmo Lupo
Inspired by the realignment or computable cross norm criterion, we present a new result about the characterization of quantum entanglement. Precisely, an interesting class of inequ…
Multipartite entangled states in particle mixing
M. Blasone, F. Dell'Anno, S. De Siena +2
In the physics of flavor mixing, the flavor states are given by superpositions of mass eigenstates. By using the occupation number to define a multiqubit space, the flavor states c…
Low noise cryogenic system for the measurement of Casimir energy in rigid cavities
Giuseppe Bimonte, Detlef Born, Enrico Calloni +6
We report on preliminary results on the measurement of variations of the Casimir energy in rigid cavities through its influence on the superconducting transition of in-cavity alumi…
Continuous variable quantum teleportation with sculptured and noisy non-Gaussian resources
F. Dell'Anno, S. De Siena, L. Albano Farias +1
We investigate continuous variable (CV) quantum teleportation using relevant classes of non-Gaussian states of the radiation field as entangled resources. First, we introduce the c…
Thermal correction to the Casimir force, radiative heat transfer, and an experiment
V. B. Bezerra, G. Bimonte, G. L. Klimchitskaya +2
The low-temperature asymptotic expressions for the Casimir interaction between two real metals described by Leontovich surface impedance are obtained in the framework of thermal qu…
Long-distance entanglement and quantum teleportation in XX spin chains
L. Campos Venuti, S. M. Giampaolo, F. Illuminati +1
Isotropic XX models of one-dimensional spin-1/2 chains are investigated with the aim to elucidate the formal structure and the physical properties that allow these systems to act a…

We present a geometric approach to the characterization of separability and entanglement in pure Gaussian states of an arbitrary number of modes. The analysis is performed adapting…

E. Ercolessi, A. Ibort, G. Marmo +1
The possibility of deforming the (associative or Lie) product to obtain alternative descriptions for a given classical or quantum system has been considered in many papers. Here we…
Ray space Riccati evolution and geometric phases for N-level quantum systems
S. Chaturvedi, E. Ercolessi, G. Marmo +3
We present a simple derivation of the matrix Riccati equations governing the reduced dynamics as one descends from the group U(N) describing the Schroedinger evolution of an N-leve…
General theory of electromagnetic fluctuations near a homogeneous surface, in terms of its reflection amplitudes

Strong Monogamy of Bipartite and Genuine Multipartite Entanglement: The Gaussian Case
Gerardo Adesso, Fabrizio Illuminati
We demonstrate the existence of general constraints on distributed quantum correlations, which impose a trade-off on bipartite and multipartite entanglement at once. For all N-mode…
