| Outline of Final Research Achievements |
Toward the realization of absorption spectrum measurement for a single molecule,
we studied on the spectrum measurement method using quantum light. First, we constructed the quantum light source and realized the high coupling efficiency to the optical fiber. Then, we constructed an absorption microscope for classical/quantum hybrid system and successfully observed non-fluorescent molecules. We also found a new method which can remove the effect of the non-unity detection efficiency of photon detectors. These results are important steps for the realization of the absorption spectrum measurement for a single molecule using quantum light. We will further expand this study by combining our quantum light source and absorption microscope.
