  0引言
  量子隐形传态是十分有趣且充满潜力的量子力学效应,其首次在1993年由Charles Bennett[1]等人提出,两个粒子(包含纠缠态)的量子隐形传态由李大创和曹卓良提出[2]。而在2015年,潘建伟、陆朝阳等人引入并成功完成了单光子多属性的量子传送[3]。本文中,我们将利用多粒子各个属性之间的张量积和贝尔基(Bell states)与标准正交基之间的幺正变换得出较为普适的量子传送表示法。

  Abstract:Objective:Finding a scheme and algebra structure of general quantum teleportation. Methods:Inductive reasoning and deductive reasoning. The equivalence between polynomial multiplication and tensor product.Results: Many-body or multi-degrees of freedom cases are generalized in multiple particles system with higher degrees of freedom, even mixed states. Conclusions:Predicting the existence of quantum teleportation of multiple particles system with higher degrees of freedom. And special cases which is proven by experiment are included.
