Imperfect Cloning Operations in Algebraic Quantum Theory

No-cloning theorem says that there is no unitary operation that makes perfect clones of non-orthogonal quantum states. The objective of the present paper is to examine whether an imperfect cloning operation exists or not in a C*-algebraic framework. We define a universal$$\epsilon $$ϵ-imperfect clon...
