Admissibility Forces the QSOT Axioms: A Closure-Based Extension of Multipartite Quantum States Over Time

This paper provides a structural extension of the recent QSOT framework for multipartite quantum states evolving over time.

We show that the axioms introduced in the original QSOT formulation are not merely sufficient assumptions, but are in fact forced by a general admissibility principle based on closure, persistence, and consistency under allowed transformations.

Using a closure-based analysis, we demonstrate that any temporally extended quantum state description that remains stable under admissible operations must satisfy the QSOT axioms. In this sense, the QSOT framework is shown to be structurally inevitable rather than model-dependent.

The result strengthens the conceptual foundations of QSOT by removing arbitrariness in the choice of axioms and situating them within a broader law-level admissibility structure. No modification of the original QSOT formalism is required; instead, its necessity is derived from general structural constraints.

This work is intended as a complementary extension to the original QSOT paper, clarifying why its axioms arise naturally and providing additional motivation for their adoption in the study of multipartite quantum systems evolving over time.

The closure principle employed here is compatible with a more general admissibility framework developed in the author’s prior work, but the present results stand independently of any such broader formalism.
