| Research Abstract |
We have developed control and detection techniques of an entangled-photon wavepacket in order to explore novel optical science in a strongly correlated photon system. We have successfully constructed a single-photon detection system with high temporal resolution, utilizing a wavelength-conversion technique at the single-photon level. Also we controlled two-photon spectral distribution of photon pairs generated form a spontaneous parametric down-conversion process, and performed four photon experiments. The resultant patterns showed quantum interference patterns with high visibilities.
