论文摘要
已承诺纠缠的光子对可为两光子吸收光谱提供可观的量子优势。但是，最近的工作挑战了先前报道的两光子吸收中量子增强的幅度。在这里，我们介绍了总和频率产生和分子吸收的实验比较，每个人都由分离的光子对驱动。我们建立了对Rhodamine-6g中纠缠二孔吸收的增强的上限，该增强率远低于先前报道的值。
Entangled photon pairs have been promised to deliver a substantial quantum advantage for two-photon absorption spectroscopy. However, recent work has challenged the previously reported magnitude of quantum enhancement in two-photon absorption. Here, we present an experimental comparison of sum-frequency generation and molecular absorption, each driven by isolated photon pairs. We establish an upper bound on the enhancement for entangled-two-photon absorption in Rhodamine-6G, which lies well below previously reported values.
