| Outline of Final Research Achievements |
In this project, we have developed an optical tweezer based single atom trap on a photonic crystal (PhC) nanofiber cavity. Fabrication of high quality PhC cavities on nanofibers was demonstrated. The cavities were designed for efficient interfacing of trapped single atoms to nanofiber guided modes. The interference between the cavity modes leading to unique spectral features was investigated. Photo-thermal stabilization of the PhC nanofiber cavities under ultra-high vacuum conditions was achieved. It was demonstrated that single atoms can be successfully trapped on the nanofiber cavity and can be observed in real-time through the fiber guided modes. This enables deterministic preparation of single atom events for quantum photonics applications on an all-fiber platform.

| Academic Significance and Societal Importance of the Research Achievements |
量子情報処理技術は従来の情報通信技術を著しく進歩させ社会に新たな価値を創造し得るものである。そのための重要な課題は、個々の量子系（原子、イオン、固体量子ビットなど）を分離し、それらをファイバ伝播光子により効率的にインターフェースすることである。本プロジェクトでは、トラップされた単一原子をファイバ導波モードに効率的にインターフェースする方法を実現し、それがリアルタイムで観測できることを実証した。本成果は、決定論的な方法で様々な量子フォトニクス実験を実行するための新しいプラットフォームを提供し、量子ネットワークのための新しい技術を可能にするものである。
