No-Cloning Theorem, Leibniz’s Principle, and the Notion of Uniqueness

Qiankai Yao, Bin Zhang, Yanwei Luo, Hui Huang
The impossibility of cloning an unknown quantum state is one of the basic rules governing quantum physics. This statement, known as the “no-cloning theorem”, prohibits perfect cloning, but doesn’t oppose approximate copying. In this paper, we will prove that, due to the uncontrollable quantum fluctuations, no perfect cloning can be achieved. Such a situation allows us to treat the no-cloning theorem as an equivalent one to Leibniz’s principle, and further unify them under the notion of uniquenes...
