| Outline of Final Research Achievements |
We propose a novel technique of Fourier transform spectroscopy, combined with two-photon quantum interference, with photon-number-resolving detection. Toward realization of this technique, we have carried out spectroscopic and interferometric quantum measurements in order to characterize spectral properties of photon pairs generated from a nonlinear crystal. The resultant spectral widths from these measurements showed consistent values. In addition, we have developed a technique to efficiently collect photon pairs from a resonant state of biexcitons in a CuCl crystal.
