摘要 利用纠缠交换的方法实现了两粒子和三粒子纠缠态的纯化,并将该方法推广到多粒子纠缠态的情况,而且得出在所有的情况下从部分纠缠态获得最大纠缠态的概率均为2|b|2。在此过程中我们只使用了幺正变换和Hadam ard变换,而不需要经典通信。 The author investigate the purification of entangled two-particle states and entangled three-particle states by entanglement swapping, then populanze it to entangled multi-particle states, and the author find that the totol probability is 2|b|^2 in all kinds of states. In the process, only the unitary transformation and Hadamard transformation are nsed.
