In physics, the no-deleting theorem of quantum information theory is a no-go theorem which states that, in general, given two copies of some arbitrary quantum ...

en.wikipedia.org/wiki/No-cloning_theorem

In physics, the no-cloning theorem states that it is impossible to create an identical copy of an arbitrary unknown quantum state. This no-go theorem of quantum mechanics was articulated by Wootters and ... generalizes this result to mixed states. The no-cloning theorem has a time-reversed dual, the no-deleting theorem.
