Is Quantum Gravity a Super-Quantum Theory?
Lay Nam Chang, Zachary Lewis, Djordje Minic, Tatsu Takeuchi

TL;DR
This paper proposes that quantum gravity is a super-quantum theory with stronger non-local correlations than standard quantum mechanics, potentially observable in entangled stringy states.
Contribution
It introduces the idea that quantum gravity may exhibit super-quantum correlations, extending beyond conventional quantum theory.
Findings
Quantum gravity may have super-correlations stronger than quantum theory.
Super-correlations could be observed in entangled stringy states.
Theoretical argument for super-quantum nature of quantum gravity.
Abstract
We argue that quantum gravity should be a super-quantum theory, that is, a theory whose non-local correlations are stronger than those of canonical quantum theory. As a super-quantum theory, quantum gravity should display distinct experimentally observable super-correlations of entangled stringy states.
