Randomized trial assesses quantum correlation limits in absolute frame theory, indicating nonlocal constraints.

This research investigates the limits of correlations in Absolute Frame Theory, specifically relating them to the Tsirelson bound.
Two independent routes were established: an operator route proving the Tsirelson operator identity and an information route reducing the bound to a physical principle.
Local commutativity was derived from AFT structure, and the information route involved a completely positive, trace-preserving channel analysis.
AFT's nonlocal correlations are shown not to exceed the Tsirelson bound of 2√2.
The findings confirm AFT's adherence to Information Causality, distinguishing it from super-quantum scenarios.
Ultimately, both approaches contribute to understanding a foundational aspect of quantum theory's limits.
