摘　　要：This paper presents a scheme for generating three-particle W state of remote atoms trapped in leaky cavities.The scheme uses cavity decay to inject photons into a setup of optical devices which consist of a series of beam splitters and photon detectors.Photon detection on the output mode projects the atomic state into the W state.In the condition of "weakly driven approach",it shows that the scheme is robust and has high fidelity.It also points out that the scheme is scalable to generate multi-atomic W state.
