No-signaling from Gleason non-contextuality and the tensor-product structure

TL;DR

This paper demonstrates that the no-signaling principle in quantum mechanics can be derived from Gleason non-contextuality combined with the tensor product structure of quantum states.

Contribution

It establishes a foundational link showing no-signaling as a consequence of non-contextuality and tensor structure, providing new insights into quantum theory foundations.

Findings

No-signaling follows from Gleason non-contextuality and tensor product structure.

Provides a derivation of no-signaling without assuming it a priori.

Highlights the foundational role of non-contextuality in quantum mechanics.

Abstract
