Bound on optimal local discrimination of multipartite quantum states

arXiv:2204.12830 · doi:10.1038/s41598-022-18496-y

Abstract

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.
