7. (Quantum Non-Cloning Theorem) In quantum mechanics, it is impossible to create a duplicate copy of an arbitrary unknown quantum state. More precisely, we may show this theorem by contradiction. That is, for an arbitrary unknown state ly), you may assume there exists a unitary operator satisfying: Uly) 10) = ly) @[p] where 10) is a vacuum state.
