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 …
Quantum Chernoff Bound metric for the XY model at finite temperature
Damian F. Abasto, N. Tobias Jacobson, Paolo Zanardi
We explore the finite temperature phase diagram of the anisotropic XY spin chain using the Quantum Chernoff Bound metric on thermal states. The analysis of the metric elements allo…
Maximally entangled fermions
Dirk-M. Schlingemann, Marco Cozzini, Michael Keyl +1
Fermions play an essential role in many areas of quantum physics and it is desirable to understand the nature of entanglement within systems that consists of fermions. Whereas the…
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…
A Continuity Theorem for Stinespring's Dilation
Dennis Kretschmann, Dirk Schlingemann, Reinhard F. Werner
We show a continuity theorem for Stinespring's dilation: two completely positive maps between arbitrary C*-algebras are close in cb-norm iff we can find corresponding dilations tha…
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…
