Peer Review of- Three Sins Against Physics by an Exaggerated Quantum Information Perspective - Valerio Scarani

This paper presents a critical analysis of Valerio Scarani's article *Three Sins Against Physics by an Exaggerated Quantum Information Perspective*. Unlike many contemporary works in quantum information theory, Scarani openly acknowledges several conceptual distortions generated by the dominance of informational and operational viewpoints in modern physics. In particular, he criticizes the confusion between optical and quantum coherence, the reduction of physical dynamics to gate-based descriptions, and the growing tendency to interpret physical reality through adversarial game-theoretic frameworks. The present review argues that these criticisms, while insightful, ultimately fail to reach the foundational source of the problems they identify. The manuscript challenges several consequences of the quantum-information paradigm while leaving untouched the deeper assumptions upon which that paradigm rests. Hilbert spaces, quantum states, Hamiltonians, coherent sectors, and admissible dynamical structures remain fully assumed rather than physically derived. It is argued that the central difficulty of modern quantum theory is not the excessive use of informational language, but the absence of a generative account of the structures being manipulated. The reviewed framework contains no derivation of coherent persistence, no principle of admissibility, no mechanism of structural selection, and no ontology capable of explaining why stable quantum states should exist in the first place. The paper further argues that many practical difficulties of quantum technologies—including decoherence, instability, correction overhead, and scalability limitations—are not independent engineering obstacles but manifestations of unresolved foundational assumptions. Scarani successfully identifies several cracks in the building of quantum information theory; however, he never questions the foundations beneath it. The review concludes that the manuscript represents an intelligent and valuable internal critique of quantum information theory, but one that remains entirely confined within the same ontological and generative assumptions that produced the distortions it seeks to correct.
