SpiruTunnel-Q A Hypothetical Bio-Quantum Platform Based on Tunneling-Enhanced Spin States in Spirulina platensis

We propose a speculative bio-quantum architecture in which a spin-based qubitemerges within a modified protein structure inside Spirulina platensis. Thesystem enhances electron and proton tunneling through a structuredhydrogen-bond network while partially preserving coherence at ambienttemperature. Recent experimental and theoretical work on microtubules(2024-2025) provides direct justification for coherence times of order T2 ~ 1 μsunder physiological conditions, supporting the key parameter choices of thismodel. A stochastic toy model incorporating tunneling, decoherence, andfluorescence is presented. Numerical simulations suggest observablenon-classical optical signatures.
