三粒子任意态的量子隐形完全传送

提出一个利用六粒子非贝尔对量子通道对一个任意的三粒子量子态进行隐形传送的方案.发送者Alice对需传送的三粒子量子态与属于自己的纠缠对中的三粒子进行三次Bell基测量，并将测量结果通过经典通道告诉接受者，接受者Bob根据这些信息对自己拥有的粒子进行Toffoli变换，就可使这三粒子处于待发送的原始量子态，从而实现概率为1的量子态隐形传送.利用变换算符的思想，很容易得出塌陷态的表达式以及接受者Bob所做的幺正变换的表达式.

Perfect Teleportation an Arbitrary Three-particle State

Considering the gain and lose of the random medium,was simulated photonic behavior of random walk in the ZnO powder laser.We studied that the laser emission demands different scatter density for different lasing mode while keeping the pump intensity and volume constant.And we gained the laser emission spectra varied with the scatter density,find that the laser action could occur when the scatter density above the critical density.When the scatter density was further increased,there are more and higher lasing peaks emerged in the emission spectra.
