- Abstract: Quantum light is a key resource for promoting quantum technology. One such
class of technology aims to improve the precision of optical measurements using
engineered quantum states of light. In this study, we investigate transmission
measurement of frequency-entangled broadband photon pairs generated via
parametric down-conversion with a monochromatic laser. It is observed that
state-to-state dynamics in the system under study are temporally resolved by
adjusting the path difference between the entangled twin beams when the
entanglement time is sufficiently short. The non-classical photon correlation
enables time-resolved spectroscopy with monochromatic pumping. It is further
demonstrated that the signal corresponds to the spectral information along
anti-diagonal lines of, for example, two-dimensional Fourier-transformed photon
echo spectra. This correspondence inspires us to anticipate that more
elaborately engineered photon states would broaden the availability of quantum
light spectroscopy.
