Toward Magnetic-Field-Free Quantum Computing and Quantum Reservoir Computing in Engineered Organic Materials: A Unified Framework from the 3-Layer Quantum Brain Hypothesis

arXiv:2605.00026v1 Announce Type: new
Abstract: We extend the spin-vortex-induced loop-current (SVILC) qubit [Wakaura2017] and the 3-Layer Quantum Brain Hypothesis to engineered organic materials operated without any applied magnetic field. Four paths are proposed: (P1) a flavin–nitroxide radical-pair reservoir, (P2) a perchlorotriphenylmethyl (PTM) radical array in a covalent organic framework, (P3) the SVILC analogue on $kappa$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Br (conditional on SVILC confirmation), and (P4) a Su–Schrieffer–Heeger soliton on trans-polyacetylene. We verify the eight SVILC conditions and benchmark five algorithms (QKAN, qDRIFT, control-free QPE, Shor–Regev, Bernstein–Vazirani) plus two ML tasks (spike prediction, MNIST) on a covariant-purification CQEC simulator. With up to 100 trials, paired Wilcoxon tests and Bonferroni correction ($alpha!=!0.05/44$), CQEC gains are significant ($p!<!10^-5$) for all 16 path$times$algorithm pairs and peak at $gamma!=!0.5$ with $Delta F!=!+0.303$ for Shor–Regev ($d!=!64$), directly confirming Petz recovery beyond the entanglement-breaking threshold. Bernstein–Vazirani yields a provable quantum advantage: P2–P4 reach CQEC-corrected one-query success rates $ge!0.95$ versus classical $2^-n$, a $7.6$–$31times$ advantage for $n!=!3$–$5$ (toy-scale benchmark). A tight-binding simulation on the anisotropic triangular lattice reproduces the two-SVQ coupling-vs-distance behaviour of [Wakaura2017] and shows that an external feeding current amplifies the coupling by $sim!1.9!times!10^3$, providing theoretical scaffolding for P3. We quantify the diarylethene photoswitch CZ fidelity ($F_mathrmCZ!ge!0.987$ for P2–P4) and compare projected manufacturing costs against five competing platforms, finding 10–40$times$ cost and 10–200$times$ power reduction.
