论文摘要
我们通过局部过滤显示了几个绑定的纠缠状态，以显示量子键分布（QKD）的可蒸馏键率的提高。通过我们的工作，很明显的是，当地过滤操作在将一个约束的纠缠状态转换为另一个纠缠状态的同时，有可能增加QKD新状态的效用。我们通过本地过滤演示了“一种一种可蒸馏的关键速率”增强的三个示例，在此过程中，发现了新的绑定纠缠状态，这些状态是可蒸馏的。
We show the enhancement of distillable key rate for quantum key distribution(QKD), by local filtering, for several bound entangled states. Through our work it becomes evident that the local filtration operations, while transforming one bound entangled state to another, have the potential to increase the utility of the new state for QKD. We demonstrate three examples of `one way distillable key rate' enhancement by local filtering and in this process, discover new bound entangled states which are key distillable.
