Over two decades, scientists have explored whether quantum mechanics plays a fundamental role in biological processes, with early enthusiasm focusing on photosynthesis experiments that suggested organisms could maintain quantum coherence to convert light to chemical energy with near‑perfect efficiency. Subsequent analyses, however, revealed that the observed signals stemmed from molecular resonances rather than long‑lived quantum coherence, leading prominent researchers such as Gregory Scholes of Princeton University to doubt that genuine quantum effects persist long enough in warm, wet cellular environments to influence biology.
Scholes and colleagues demonstrated that specifically constructed networks of classical oscillators can produce emergent, stable patterns of synchronized behavior—like a crowd clapping in time—that are mathematically describable as vectors in a Hilbert space, the same abstract framework used to represent quantum states. By tuning the network’s topology, they showed these emergent states can mimic the simplest quantum unit, a qubit existing in superposition of two states, arising purely from classical interactions without invoking any genuine quantum phenomena, a point noted by physicist Markus Müller and quantum chemist Sabre Kais.
The authors stress that these states are only 'quantumlike,' not true quantum states, and emphasize that no study to date has shown such mathematical mimicry conferring a functional advantage in living systems; Scholes provocatively suggests that, at the largest scales, quantum biology might mean using three and a half billion years of evolution to engineer the functionality that quantum systems provide, leaving open the question of how widespread or consequential this effect truly is in actual biological contexts.
