Engineering of Stationary Entanglement Between Distant Atoms Coupled to a Cavity Field
Z. Ficek · 2008
We study the feasibility of the commonly used adiabatic techniques in the atom-cavity field interaction to entangle two distant atoms trapped inside an optical cavity. Two techniques are considered: the first involves a highly detuned cavity from the atomic transition frequencies, and the second involves a near resonant but strongly damped cavity. We find that the second technique is more efficient for creation of a controllable entanglement between the atoms. We follow the temporal evolution of the concurrence and show that the system evolves to a single entangled state whose the stationary population is a sensitive function of the initial state of the atoms and strengths of the couplings of the atoms to the cavity mode.
