Generation of entanglement molecules via weak coherent field in cavity QED

doi:10.1088/1674-1056/18/2/034

Abstract

Abstract This paper presents a method for generating entanglement molecules, which is introduced by Dur (2001 Phys. Rev. A). In this scheme, N ladder-type three-level atoms are sent through a resonant weak coherent cavity field, then the system states are measured. And the system field may collapse onto some possible types of entanglement molecules. Meanwhile it discusses about the interaction time from the experimental point of view, and compare the result with the previous scheme proposed by Huang (2004 J. Phys. B: At. Mol. Opt. Phys.).

Keywords: weak coherent state resonant interaction entanglement molecules
