Local expansion of atomic W state in cavity quantum electrodynamics

Local expansion of atomic W state in cavity quantum electrodynamics

Based on resonant interactions between atoms and cavity modes, we have designed a scheme for expanding atomic entangled W states. By sending one of the atoms in a N -atom W state and an auxiliary excited-state atom into an vacuum cavity, we have obtained a ( N  + 1)-atom W state by detecting the cav...

Zusammenfassung:Based on resonant interactions between atoms and cavity modes, we have designed a scheme for expanding atomic entangled W states. By sending one of the atoms in a N -atom W state and an auxiliary excited-state atom into an vacuum cavity, we have obtained a ( N  + 1)-atom W state by detecting the cavity field after interaction. The feasibility analysis indicates that this scheme may be implementable in near future.
