Building an entanglement measure on physical ground
D. Teresi, A. Napoli, A. Messina
We introduce on physical grounds a new measure of multipartite entanglement for pure states. The function we define is discriminant and monotone under LOCC and moreover can be expr…
Quantum light depolarization: the phase-space perspective
A. B. Klimov, J. L. Romero, L. L. Sanchez-Soto +2
Quantum light depolarization is handled through a master equation obtained by coupling dispersively the field to a randomly distributed atomic reservoir. This master equation is so…
A criterion for entanglement in two two-level systems
E. Ferraro, A. Napoli, A. Messina
We prove a necessary and sufficient condition for the occurrence of entanglement in two two-level systems, simple enough to be of experimental interest. Our results are illustrated…
Distillation of Entanglement between Distant Systems by Repeated Measurements on Entanglement Mediator
G. Compagno, A. Messina, H. Nakazato +3
A recently proposed purification method, in which the Zeno-like measurements of a subsystem can bring about a distillation of another subsystem in interaction with the former, is u…
Loss induced collective subradiant Dicke behaviour in a multiatom sample
S. Nicolosi, A. Napoli, A. Messina
The exact dynamics of two-level atoms coupled to a common electromagnetic bath and closely located inside a lossy cavity is reported. Stationary radiation trapping effects are…
