| Outline of Final Research Achievements |
Along with the recent experimental progress on fundamental quantum physics and quantum info-communication technology, development of high-performance single-photon sources is demanded. In this project, we carried out exploratory research aiming at the generation of mutually-coherent single photons and the development of high-performance single-photon sources using hydrogen-atom endohedral C60 (N@C60) synthesized by the plasma ion irradiation method.
The research subjects are (1) search of single photon emission from N@C60 at room temperature, (2) development of confocal micro-spectrograph to observe single-photons at low temperature, and (3) development of an efficient coupling system between single photon emitters and optical nano-fiber.

| Academic Significance and Societal Importance of the Research Achievements |
研究期間内には企図したN@C60からの単一光子発光を確認することはできなかったが，本研究で開発した低温下単一光子分光測定システムや単一光子源とナノ光ファイバとの高効率結合に向けた研究成果は，今後の高効率単一光子源の開発や新たな単一光子発生系の研究を促し，基礎量子物理学や量子情報通信技術の実験的研究の発展に寄与するものである．
