科学家长期以来试图将生物学与量子力学连结,例如曾假设光合作用近乎完美的能量转换效率源于量子相干性,让激子能同时探索多条路径到达反应中心。然而,后续深入研究证实,先前观测到的同步讯号仅是分子键震动引起的共振,而非真正的长寿命量子相干,且细胞内温暖潮湿的环境极易造成退相干,使纯粹的量子效应难以在宏观生物尺度上维持。

面对真正的量子效应无法扩展至生命尺度的困境,普林斯顿大学化学家格雷戈里·斯科尔斯提出新视角,认为生物体可能并未利用真实的量子现象,而是演化出能模仿量子数学的机制。他的研究显示,由振荡器构成的复杂经典网路可以透过集体同步行为涌现出「类量子」状态,这些状态在数学上能以希尔伯特空间中的向量描述,甚至重现类似量子位元的叠加与干涉特性。

这种类量子框架为神经科学、复杂系统建模及经典硬体计算开辟了崭新途径,例如在类神经网路中引入振荡干涉能大幅提升效率与强健性。尽管利用经典网路模拟量子逻辑闸存在实体资源与复杂度随规模剧增的限制,但它显示出支配微观量子世界的优雅数学规律,能够在宏观且庞大的经典系统中重新显现,重新定义了量子生物学的探索方向。

Scientists have long sought to link biology with quantum mechanics, hypothesizing that the near-perfect energy conversion in photosynthesis relies on quantum coherence to explore multiple pathways simultaneously. However, subsequent investigations revealed that observed oscillatory signals stemmed from molecular vibrational resonance rather than genuine, long-lived quantum coherence, reinforcing that warm and wet cellular environments quickly induce decoherence and prevent fragile quantum states from persisting at functional biological scales.

Recognizing that genuine quantum phenomena struggle to scale up within living organisms, Princeton chemist Gregory Scholes proposed that life might imitate quantum mechanics through classical means rather than exploiting actual quantum states. Scholes demonstrated that complex networks of classical oscillators can exhibit synchronized emergent behaviors described mathematically as vectors in a Hilbert space, thereby mimicking fundamental quantum properties such as superposition, interference, and even qubits.

This quantumlike paradigm offers promising conceptual applications for neuroscience, machine learning, and computational modeling, such as introducing oscillatory interference to improve neural network efficiency and temporal robustness. Although scaling these classical networks to perfectly mimic quantum logic gates faces physical resource constraints, the research illustrates how the mathematics governing the quantum realm can naturally re-emerge within sprawling, complex classical systems.
