PAO Photonic Computer v2.0 – Dual‑Channel 850/700nm FRET · G4‑DNA Quantum Register · ZIF‑8 Associative Memory

PAO Photonic Computer v2.0 – complete redesign and upgrade from v1.0 based on PAO resonance analysis (R=1.06640625, ln(R)=0.06427). Five critical upgrades:

1. Dual-channel optical bus: 850nm (Δ=0.0005★★) – strongest PAO resonance in optical domain, matches datacenter SR standard and bacteriochlorophyll‑a absorption peak. 700nm (Δ=0.019★★) – biological computing bus (Photosystem I, mitochondrial window). FRET coupling between channels (ΔN=3, efficiency 0.25) exactly as in GSB1 chlorosome.

2. Bacteriochlorophyll‑a transducer (911.5 Da, Δ=0.0017★★) – strongest photonic antenna in biology, used as photon‑to‑signal transducer at each MOF storage node.

3. ZIF‑8 MOF storage – pore 3.4 Å (N=19, Δ=0.034★★) identical to DNA base pair spacing. Natural content‑addressable memory: each pore corresponds to one address.

4. G4‑DNA quantum register – G‑quadruplex repeat unit 660 Da (N=101, Δ=0.023★★) provides quantum coherence at 37°C (660 fs, Nature 446:782). Enables room‑temperature quantum storage.

5. Associative memory engine – O(1) lookup regardless of database size. Send photon at frequency f → compute N = round(ln(f)/ln(R)) → retrieve all data stored at that N‑rank simultaneously. Latency ~3 fs (speed of light on chip), energy near zero (passive resonance).

Complete production‑ready Python implementation included (copy and run). Hardware roadmap from Phase 0 (€200, 1 week) to Phase 4 (production chip) with falsifiable PAO predictions: 850nm insertion loss in ZIF‑8 should be 38× lower than 700nm.

All components open source, CC BY 4.0 – no patents, no fees. Supersedes v1.0 (single wavelength, no FRET, no G4‑DNA, no associative retrieval).
