An experimental apparatus for measuring the Casimir effect at large distances

P Antonini, G Bimonte, G Bressi +4

An experimental set-up for the measurement of the Casimir effect at separations larger than a few microns is presented. The apparatus is based on a mechanical resonator and uses a…

On the relation between Schmidt coefficients and entanglement

Paolo Aniello, Cosmo Lupo

We consider the Schmidt decomposition of a bipartite density operator induced by the Hilbert-Schmidt scalar product, and we study the relation between the Schmidt coefficients and…

Polarized thermal emission by thin metal wires

Giuseppe Bimonte, Luca Cappellin, Giovanni Carugno +2

We report new measurements of the linear polarization of thermal radiation emitted by incandescent thin tungsten wires, with thicknesses ranging from five to hundred microns. Our d…

Unital Positive Maps and Quantum States

M. Asorey, A. Kossakowski, G. Marmo +1

We analyze the structure of the subset of states generated by unital completely positive quantum maps, A witness that certifies that a state does not belong to the subset generated…

Semigroup of positive maps for qudit states and entanglement in tomographic probability representation

V. I. Man'ko, G. Marmo, A. Simoni +1

Stochastic and bistochastic matrices providing positive maps for spin states (for qudits) are shown to form semigroups with dense intersection with the Lie groups $IGL(n, \mathbb{R…

Optimal estimation of losses at the ultimate quantum limit with non-Gaussian states

G. Adesso, F. Dell'Anno, S. De Siena +2

We address the estimation of the loss parameter of a bosonic channel probed by arbitrary signals. Unlike the optimal Gaussian probes, which can attain the ultimate bound on precisi…

Casimir effect in a superconducting cavity and the thermal controversy

Giuseppe Bimonte

One of the most important and still unresolved problems in the field of dispersion forces, is that of determining the influence of temperature on the Casimir force between two meta…

Basics of Quantum Mechanics, Geometrization and some Applications to Quantum Information

J. Clemente-Gallardo, G. Marmo

In this paper we present a survey of the use of differential geometric formalisms to describe Quantum Mechanics. We analyze Schrödinger framework from this perspective and provide…

Genuine multipartite entanglement of symmmetric Gaussian states: Strong monogamy, unitary localization, scaling behavior, and molecular sharing structure

Gerardo Adesso, Fabrizio Illuminati

We investigate the structural aspects of genuine multipartite entanglement in Gaussian states of continuous variable systems. Generalizing the results of [Adesso & Illuminati, Phys…

Symplectic tomography of ultracold gases in tight-waveguides

A. del Campo, V. I. Man'ko, G. Marmo

The phase space is the natural ground to smoothly extrapolate between local and non-local correlation functions. With this objective, we introduce the symplectic tomography of many…

Frame transforms, star products and quantum mechanics on phase space

P. Aniello, V. I. Man'ko, G. Marmo

Using the notions of frame transform and of square integrable projective representation of a locally compact group , we introduce a class of isometries (tight frame transforms)…
