摘　　要：在腔中通过双Raman作用,在超导量子干涉器件中实现多比特GHZ(Greenberger-Horne-Zeilinger)态的制备.在制备过程中,由于腔场只是被虚激发的,所以腔模的衰减可以忽略.GHZ态的实现只用到了超导系统的两个基态,有效地避免了超导系统激发态的弛豫.Propose a scheme to realize multi-qubit GHZ states in superconducting quantum-interference devices（SQUIDs） via double Raman transition.In this scheme,the cavity field is only virtually excited and thus the cavity decay can be ignored.The GHZ states are realized by using only two basic states of the SQUID system and the relaxation of excited state of the system are avoided.Base on the points mentioned above,the scheme should be easily realized on experiment.
