- TL;DR Summary
- Looking for papers on two things: (1) fully deterministic systems where Kolmogorov-complexity entropy provably rises every step, no coarse-graining, just algorithmic arguments (beyond Gács 2023 or ’t Hooft); (2) deterministic, signal-local models that hit the CHSH Tsirelson limit (2√2) by violating measurement independence rather than locality. Any leads appreciated!
Hi everyone. I’m exploring deterministic causal-graph models and have two literature questions.
(1) Entropy: In a finite automaton an observer restricted to a coarse region sees Kolmogorov-complexity entropy rise each update. M. Gács (“The Algorithmic Second Law of Thermodynamics,” Entropy 25) and ’t Hooft discuss similar ideas. Are there modern proofs of a monotone second law that stay fully deterministic and avoid coarse-graining?
(2) Tsirelson bound: This is the part that really puzzles me. My local, synchronous update model outputs CHSH = 2√2 when averaged over its hidden states. The potential loophole is that the choice of measurement settings is correlated with the system's pre-existing local state information, which could be a violation of the Measurement Independence assumption in Bell's theorem. Are there known deterministic models that can saturate the quantum bound specifically via this kind of loophole?
Any pointers or critique welcome, thanks!
