Discrete Wigner distribution for two qubits: a characterization of entanglement properties
R. Franco, V. Penna
We study the properties of the discrete Wigner distribution for two qubits introduced by Wotters. In particular, we analyze the entanglement properties within the Wigner distributi…
Canonical quantization of nonlinear many body systems
A. M. Scarfone
We study the quantization of a classical system of interacting particles obeying a recently proposed kinetic interaction principle (KIP) [G. Kaniadakis, Physica A {\bf 296}, 405 (2…
Mode transformations and entanglement relativity in bipartite gaussian states
Emanuele Ciancio, Paolo Giorda, Paolo Zanardi
A proper choice of subsystems for a system of identical particles e.g., bosons, is provided by second-quantized modes i.e.,creation/annihilation operators. Here we investigate how…
Decoherence-Free Emergence of Macroscopic Local Realism for entangled photons in a cavity
S. Portolan, O. Di Stefano, S. Savasta +2
We investigate the influence of environmental noise on polarization entangled light generated by parametric emission in a cavity. By adopting a recently developed separability crit…
