Bounds on action of local quantum channels

Original language description

We derive an upper bound on the action of a direct product of two quantum maps (channels) acting on bi-partite quantum states. Our results show that the fundamental distinction between the set of separable and the set of entangled states results in two different bounds which in turn can be exploited for discrimination between the two sets of states. We generalize our results to multi-partite channels.
