英文摘要	We present a scheme to prepare two-atom Einstein-Podoisky-Rosen states and three-atom entangled states via cavity quantum electrodynamics, and it can be realized experimentally. Importantly, we find that in the set of tripartite entangled states prepared by our scheme there is a peculiar tripartite entangled state except the Greenberger-Horne-Zeilinger (GHZ) state. The peculiar tripartite entangled states have double feature of the GHZ state (i.e. tau(123) > 0) and W state (i.e. the remaining reduce density matrices rho(ij) retain entanglement according to the positive partial transformation (PPT) criterion) simultaneously. However, its entanglement properties are not completely identical either to the GHZ state or to the W state. It is interesting that for peculiar entanglement properties, the remaining reduced density matrices rho(ij) can retain entanglement or disentanglement independently, which can be chosen freely according to our need.
