利用自发参量下转换产生的频率纠缠宽带光子对进行量子光谱分析。在空闲光子探测器前放置吸收样品，用衍射光栅对信号光子的频率进行分辨。通过计算符合数对样品的吸收光谱进行了测量，结果与传统分光光度计在经典光源下测量的结果一致。
Quantum spectroscopy was performed using the frequency-entangled broadband photon pairs generated by spontaneous parametric down-conversion. An absorptive sample was placed in front of the idler photon detector, and the frequency of signal photons was resolved by a diffraction grating. The absorption spectrum of the sample was measured by counting the coincidences, and the result is in agreement with the one measured by a conventional spectrophotometer with a classical light source.
