Classical no-cloning theorem.

چکیده
A classical version of the no-cloning theorem is discussed. We show that an arbitrary probability distribution associated with a (source) system cannot be copied onto another (target) system while leaving the original distribution of the source system unperturbed. For classical dynamical systems such a perfect cloning process is not permitted by the Liouvillian (ensemble) evolution associated with the joint probability distribution of the composite source-target-copying machine system.

متن کاملClassical no-cloning under Liouville dynamics by non-Csiszár f-divergence
Abstract. The Csiszár f-divergence, which is a class of information distance, is known to offer the classical counterpart of the quantum impossible cloning operations for the factrized and marginality classical probability distributions under Liouville dynamics. We show that a class of information distance belonging not to this divergence class also provides the classical version of the no-clon...
متن کاملNon-classical conditional probability and the quantum no-cloning theorem
The quantum mechanical no-cloning theorem for pure states is generalized and transfered to the quantum logics with a conditional probability calculus. This is, on the one hand, an extension of the classical probability calculus and, on the other hand, a mathematical generalization of the Lüders von Neumann quantum measurement process. In the non-classical case, a very special type of conditiona...
متن کاملClassical and quantum: some mutual clarifications
This paper presents two unconventional links between quantum and classical physics. The first link appears in the study of quantum cryptography. In the presence of a spy, the quantum correlations shared by Alice and Bob are imperfect. One can either process the quantum information, recover perfect correlations and finally measure the quantum systems; or, one can perform the measurements first a...
متن کاملClassical Coding and the Cauchy-schwarz Inequality
In classical coding, a single quantum state is encoded into classical information. Decoding this classical information in order to regain the original quantum state is known to be impossible. However, one can attempt to construct a state which comes as close as possible. We give bounds on the smallest possible trace distance between the original and the decoded state which can be reached. We gi...
