摘要
在 EPR 对由二个聚会(艾莉斯和 Debbie ) 分享了， GHZ 纠缠了三个聚会(鲍勃和克莱尔艾莉斯) 分享的状态的地方，我们为控制纠纷交换连续变量建议一个计划被要求。EPR 状态的一根光横梁将被纠缠，产量模式在克莱尔的帮助下由鲍勃代替了。交换的纠纷能发生，这被显示出由第三方(克莱尔) 控制了。
We propose a scheme for controlled entanglement swapping of continuous variable, where an EPR pair shared by two parties （Alice and Debbie） and a GHZ entangled state shared by three parties （Alice, Bob and Claire） are required. One optical beams of the EPR state will be entangled with the output mode displaced by Bob with the help of Claire. It is shown that the entanglement swapping can occur controlled by the third party （Claire）
