Abstract: | This paper proposes a simple scheme for generating a three-atom GHZ
state via cavity quantum electrodynamics (QED). The task can be
achieved through the interaction between two EPR states, which can be
prepared easily with current technology. In this scheme, the cavity
field is only virtually excited during the interaction process, and
no quantum information transfer between the atoms and the cavity is
required. Thus it greatly prolongs the efficient decoherent time.
Moreover, this scheme is also applicable for generating an N-atom
GHZ state. |
