Steady State Entanglement in Cavity QED.
We investigate steady state entanglement in an open quantum system, specifically a single atom in a driven optical cavity with cavity loss and spontaneous emission. The system reaches a steady pure state when driven very weakly. Under these conditions, there is an optimal value for atom-field coupling to maximize entanglement, as larger coupling favors a loss port due to the cavity enhanced spo...
متن کاملAdiabatic entanglement in two-atom cavity QED
We analyze the problem of a single mode field interacting with a pair of two level atoms. The atoms enter and exit the cavity at different times. Instead of using constant coupling, we use time-dependent couplings which represent the spatial dependence of the mode. Although the system evolution is adiabatic for most of the time, a previously unstudied energy crossing plays a key role in the sys...
متن کاملCross-correlations and Entanglement in Cavity Qed
Title of dissertation: CROSS-CORRELATIONS AND ENTANGLEMENT IN CAVITY QED Matthew L. Terraciano, Doctor of Philosophy, 2006 Dissertation directed by: Professor Luis A. Orozco Department of Physics Every quantum system subjected to measurements is an open quantum system. The cavity QED system is elegant in that it probes the interaction between two quantum systems, the atom and the field, while i...

Multiparticle Entanglement
The Greenberger ± Horne ± Zeilinger state is the most famous example of a state with multiparticle entanglement . In this article we describe a group theoretic framework we have been developing for understanding the entanglement in general states of two or more quantum particles. As far as entanglement is concerned, two states of n spin-1/2 particles are equivalent if they are on the same orbit...
