Outline of Final Research Achievements

The novel entangled photon probe is proposed using two photon interference by entangled photon pairs to establish the quantum optical metrology. Recently, atomic scale analysis of machining process phenomenon is required to improve material removal controllability with nanometer resolution. Therefore, the quantum optical phenomena, such as typical entanglement, are introduced to enhance the resolution of the optical measurement technique drastically. The interest in entanglement has been stimulated by the possibility that entangled photon pairs might beat the diffraction limit. We have proposed a light source for the generation of the polarization-entangled photon pairs (PEPP) by using a nonlinear crystal BiBO. For development of the light source, the geometrical parameters of the crystal are designed. The constructed light source is confirmed to generates entangled photons pairs by measuring the PEPP using a time-correlated coincidence system.

Academic Significance and Societal Importance of the Research Achievements

原子構造体(工具)と原子構造体(被加工物)の力学的相互作用による加工機序を解明する研究は,これまで分子動力学シミュレーションが用いられてきた.しかし,SEM内切削実験以外の実験的な検証方法は未だ確立されていないのが現状である.本研究成果である計量ドレスト光子プローブ計測によって加工機構が解明され,原子構造体スケールの局所的なフォノン制御を実時間で行うことが可能となれば,機械加工プロセスを原子スケールで局所化できるナノ機械加工・計測融合工学の手法に基づく新しい機械加工原理を創成し,従来技術の限界のブレークスルーが期待される.
