AI 中文摘要
极化子架构试图通过将局域自由度与离域光学腔场混合来设计分子特性。然而，标度律对N分子集体强耦合造成严重瓶颈，因为每个分子对集体态的贡献仅为一小部分，局域响应会经历O(1/N)的系综稀释。我们利用振动强耦合下分子系综的荧光编码红外光谱证明了这种标度律的违反，其中宏观同步的电子响应按O(1)标度。这种标度不变性揭示了振动量子转导机制，即非局域振动纠缠转化为集体电子纠缠。这些结果为室温量子技术和非绝热化学途径的相干控制提供了一个可扩展框架。
英文摘要
Polaritonic architectures seek to engineer molecular properties by hybridizing localized degrees of freedom with delocalized optical cavity fields. However, scaling laws impose a severe bottleneck on N-molecule collective strong coupling: because each molecule contributes only a fractional share to the collective state, localized responses undergo O(1/N) ensemble dilution. We demonstrate a violation of this scaling using fluorescence-encoded infrared spectroscopy of molecular ensembles under vibrational strong coupling, where macroscopically synchronized electronic responses scale as O(1). This scale-invariance reveals a regime of vibronic quantum transduction, where non-local vibrational entanglement is translated into collective electronic entanglement. By demonstrating the generation of macroscopically entangled electronic states from vibro-polaritons without an O(1/N) penalty, these results provide a scalable framework for room-temperature quantum technologies and coherent steering of non-adiabatic chemical pathways.
