Gregory Scholes once pursued the idea that photosynthesis preserves quantum coherence at room temperature. The experimental “beats” that energized the field in 2007 were later traced largely to ordinary molecular vibrations. His newer work takes a more interesting route: classical networks of coupled oscillators can settle into collective states represented in the same Hilbert-space mathematics used for qubits, including superposition-like interference. Quanta’s account is unusually good at separating the formal analogy from the physics.
The qualification is severe and productive. These networks are not quantum, and perfectly reproducing quantum logic can require resources that blow up with system size. The framework may still explain why oscillating neural or biological networks gain robustness and an extra temporal dimension without invoking fragile coherence in a warm cell. It also offers a filter for grander “quantum biology” claims: identical state-space geometry does not imply identical microscopic machinery.
