Generation of entanglement molecules via weak coherent field in cavity QED
Wan-Jun Su, Zhen‐Biao Yang, Huai‐Zhi Wu · Chinese Physics B · 2009
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. ).
