Generating Entangled States of Multilevel Atoms through a Selective Atom-Field Interaction
-
Abstract
We present a scheme to generate entangled state of two multilevel atoms in a high-Q optical cavity. In the protocol, the selective atom-field interaction is highly controlled, which can yield a resonant interaction inside one selected atom-field subspace and leave the others in a highly dispersive regime. The atomic spontaneous emission is efficiently suppressed via the large atom-field detuning. Simultaneously, the proposal only requires commonly addressing on atoms inside the cavity, which reduces the difficulties of experiment. -
