We present an experimental scheme of preparing the Greenberger–Horne–Zeilinger (GHZ) state and the W state with distant atoms trapped in spatially separate cavities by detecting cavity decay through single-photon detectors, based on the original ideas of photon-interference-induced entanglement between bipartite (Feng X L, Zhang Z M, Li X D, Li S D, Gong S Q and Xu Z Z 2003 Phys. Rev. Lett. 90 217902). The scheme can be generalized to prepare the general n-qubit GHZ state and W state.
