Abstract
A quantum absorption spectroscopy system () includes a laser light source (), a quantum optical system (), a photodetector (), and a controller (). The laser light source () emits pump light. The quantum optical system () includes a nonlinear optical crystal () that generates a quantum entangled photon pair of a signal photon and an idler photon by irradiation with pump light, and a moving mirror () that changes a phase of the idler photon, and causes quantum interference between a plurality of physical processes in which the quantum entangled photon pair is generated. The photodetector () detects the signal photon when the phase of the idler photon is changed by the nonlinear optical crystal () in a state where a sample is disposed on an optical path of the idler photon, and outputs a quantum interference signal corresponding to the detected number of photons. The controller () calculates an absorption spectroscopy characteristic of the sample by performing Fourier transform on the quantum interference signal.
