Research Topics
(Japanese)
確率システムおよび量子動的システムのロバスト推定およびロバスト制御理論の構築
(English)
Robust filtering and control theory for stochastic and open quantum systems
Overview of the research
(Japanese)
次世代情報技術としての量子情報処理技術の発展は目覚しく,よりよい精度の実験を行うためにも,微細な対象物への計測・制御技術はますます重要になっている.本研究では,確率システムや量子動的システムの推定や制御技術のための理論を構築することを目的とし,測度論や非可換確率論を基礎としつつ,既存の計算技術や量子計算などの次世代計算技術と理論を融合させた,実践的かつロバストな確率・量子制御理論の構築を目指している.
(English)
My research interests are in estimation and control of stochastic dynamical systems, in particular, quantum dynamical systems, and their applications to quantum information technology. My research interests are mathematics related to quantum and probability theory, which includes stochastic calculus, quantum stochastic calculus, classical and quantum statistics, the theory of operator algebras, and optimization theory, and also applications to implement quantum information technology (e.g., quantum computation and quantum communication).
