Outline of Final Research Achievements

Spins of holes in semiconductor quantum dots have the potential for high-speed manipulation through AC electric fields mediated by spin-orbit interactions, making them promising candidates for integrated qubits. However, research on the dynamics of hole spins is still in its early stages. In this study, we develop techniques for measuring hole spin dynamics and investigate their underlying physics. We newly developed group-IV semiconductor quantum dots, such as silicon and germanium quantum dots, and examined the physics related to spin qubits. In parallel with the development of machine learning techniques and qubit operations for large-scale integration, we successfully demonstrated spin manipulation based on spin-orbit interactions and fast and precision readout of quantum states, obtaining foundational results for integrated hole spin qubits.

Academic Significance and Societal Importance of the Research Achievements

本研究は、量子ビット集積化に向け優位な特性を持つ正孔スピンについて、ダイナミクスに関わる物理を調べる基盤的な研究である。シリコン量子構造中の正孔スピンの操作に成功しており、量子構造中においてはスピン軌道相互作用がバルク中とは異なることを示唆する結果が得られ、新分野の開拓に繋がる重要な学術的成果を挙げている。量子状態の高速読み出しや、デジタル信号処理による高精度読み出し、機械学習による量子ドットの電荷状態の調整補助なども実現した。さらに社会的に実現が期待されている誤り耐性量子コンピュータに向けた要素技術として、2量子ビット操作と誤り訂正の実証といったインパクトあるスピン量子ビット研究を遂行した。
