Bound on local minimum-error discrimination of bipartite quantum states
arXiv:2112.14424 · doi:10.1103/PhysRevA.105.032421
Abstract
We consider the optimal discrimination of bipartite quantum states and provide an upper bound for the maximum success probability of optimal local discrimination. We also provide a necessary and sufficient condition for a measurement 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 an example.
