摘　　要：纠缠W态是量子通信的关键资源,而融合技术已被证明是制备大规模纠缠W态的有效方法.简要综述几类重要的有粒子损失的W态融合方案及相互关系,并着重阐述无粒子损失的W态融合方案及其物理原理,最后给出总结与展望.The entangled W state is a key resource in quantum communication, while fusion technology has been proved to be an efficient way to prepare large-scale entangled W states. In this paper, we briefly reviewed several crucial W state fusion schemes with particle loss and explained their correlations, and focused on qubit-loss-free （QLF） fusion schemes of W state and their underlying physical principles. The summary and possible future directions were given at last.
