Controlling dipole squeezing of entangled atoms via superposition coherent state field
Zhihua Liu · Chinese Journal of Quantum Electronics · 2008
Considering two two-level atoms (A and B) initially in the EPR state,atom B is put into one cavity prepared in coherent superposition state.When atom B flies out of the cavity,an arbitrary state measurement is carried out on it.The law about the effects on the dipole of atoms A exerted by light field intensity and superposition coefficients is obtained,and the result also shows that the dipole squeezing of atoms A can be achieved under certain conditions.
