Are there basic laws of quantum information processing?

Abstract

We prove within the standard quantum formalism without reduction postulate that the no-cloning theorem and the principle of no-increasing of entanglement under local actions and one-way classical communication are equivalent. We argue that the result is a manifestation of more general principles governing quantum information processing analogous to the thermodynamical laws.

RevTeX, 16 pages, the proof of the theorem has been written mathematically; the possible interpretation of the result (basing on the analogy with thermodynamics) has been added; the previous discussion has been removed
