摘　　要：提出一种N粒子任意未知态的表述形式。应用这种表述形式，提出一个以N组三粒子W态的直积态作为信道的N粒子未知态的隐形传送方案。通过Alice的Bell基测量和Bob的计算基测量及幺正变换，实现N粒子任意未知态的概率传送。这种方案成功实现的概率为（2／3）^N。A representation of an N-particle arbitrary and unknown state is proposed. As an application, a scheme for teleporting an N-particle unknown state via the product state of W states is investigated. The teleportation scheme of an N-particle unknown state can be realized by Alice＇s Bell-state measurements and Bob＇s computation basis measurements and unitary transformations with the probability of the successful teleportation （2/3）N.
