Storing Quantum Information in a generalised Dicke Model via a Simple Rotation
R. López-Peña, S. Cordero, E. Nahmad-Achar +1
A method for storing quantum information is presented for -level atomic systems interacting dipolarly with a single radiation field. The method involves performing simple local…
Wigner Function Analysis of Finite Matter-Radiation Systems
E. Nahmad-Achar, R. López-Peña, S. Cordero +1
We show that the behaviour in phase space of the Wigner function associated to the electromagnetic modes carries the information of both, the entanglement properties between matter…
Geometry, quantum correlations, and phase transitions in the -atomic configuration
O. Castaños, S. Cordero, R. López-Peña +1
The quantum phase diagram for a finite -level system in the configuration, interacting with a two-mode electromagnetic field in a cavity, is determined by means of informati…
