Show HN: Lorentzian CSS Duality in Causal Diamond Quantum Error-Correcting Codes

This GitHub repo proposes a new mathematical equivalence ("duality") between CSS codes — a standard family of quantum error-correcting codes used to protect quantum information — and causal diamonds, a concept from relativity describing the region of spacetime any observer can influence. The "Lorentzian" part refers to special relativity's spacetime geometry. This sits within an active research area connecting quantum information theory (error correction) to spacetime and gravity (the holographic principle, black hole information). The author is sharing outside the peer-reviewed system, so the claims should be treated as unverified frontier theory.
