Preparation of multi-party entanglement of individual photons and atomic ensembles

Abstract An experimental feasible scheme is proposed to generate Greenberger–Horne–Zeilinger (GHZ) type of maximal entanglement. Distinguishing from the previous schemes, this entanglement can be chosen between either atomic ensembles (stationary qubit) or individual photons (flying qubit), according to the difference applications we desire for it. The physical requirements of the scheme are moderate and well fit the present experimental technique.
