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 can not be copied in general, they can not be broadcast. For mixed states, it generalizes no-cloning.
