Outline of Research at the Start

量子もつれを利用してターゲットを高精度に検出できる量子イルミネーションをはじめ,量子技術を使った超精密計測への期待は,目下大きな高まりを見せている.量子計測の実験は近年とくに盛んになっているが,極限性能への追求にあたり莫大なコストが前提となっている.本研究では,エネルギーコスト削減をはじめ様々な実用的なニーズに応え,擬似ベル状態を用いた量子イルミネーションに向けた測定器の物理的構成の解明及びその最適化を行い,測定器の設計手法を開発する.

Outline of Final Research Achievements

Quantum illumination is an entanglement-based protocol that is able to detect the existence of a target. In this study, we considered and discussed a physical implementation of a measurement scheme for the quasi-Bell state-based quantum illumination in an attenuation environment using a beam splitter and photon counters. As a result, under almost all conditions, the scheme offers a significant advantage over a scheme using the two-mode squeezed vacuum state, which allows optimum quantum detection. In addition, it was clarified that similar performance can be obtained by replacing the photon counters with on-off detectors.

Academic Significance and Societal Importance of the Research Achievements

エンタングルド状態という量子力学的な相関状態を用いて,物体の存在,状態,形状等を高感度あるいは高精度に計測する技術が量子計測技術である.本研究の成果により,擬似ベル状態などの非ガウス状態を用いた量子計測プロトコルでは,より経済的な素子で測定器を構成する可能性があること,2モードスクィズド真空状態などのガウス状態を用いたプロトコルより優れた性能を出しうることを示唆しており,非ガウス状態の生成,応用プロトコルの性能解析や技術開発などに関する研究の加速を促すことが期待される.
