论文摘要
我们考虑对多方量子状态的明确歧视,并为最佳局部歧视的最大成功概率提供了上限。我们还提供了实现上限的必要条件。我们进一步建立了该上限饱和的必要条件。最后,我们使用多维多部分量子系统中的示例说明了结果。
We consider the unambiguous discrimination of multipartite quantum states and provide an upper bound for the maximum success probability of optimal local discrimination. We also provide a necessary and sufficient condition to realize the upper bound. We further establish a necessary and sufficient condition for this upper bound to be saturated. Finally, we illustrate our results using examples in multidimensional multipartite quantum systems.
