Quantum infrared spectroscopy enables infrared spectroscopy using only visible light sources and detectors utilizing quantum-correlated visible-IR photon pairs. Here, we theoretically and experimentally show that the quantum Fourier-transform infrared spectroscopy is capable of high spectral resolution measurements even under pulsed pumping with a finite spectral linewidth, contrary to conventional expectations. This result opens the new direction for high-spectral-resolution ultrafast IR spectroscopy with femtosecond time resolution with a simple and compact setup just using visible detectors, thus significantly advancing quantum sensing technology and introducing new engineering capabilities to a wide range of research fields from physics, chemistry and environmental science.
