No-broadcast theorem

From Wikipedia, the free encyclopedia

The no-broadcast theorem is a result in quantum information theory. In the case of pure quantum states, it is a corollary of the no cloning theorem: since quantum states cannot be copied in general, they cannot be broadcast. For mixed states, it generalizes no-cloning.
