• Ohki gave a presentation about model order reduction at IFAC World Congress 2026 in Busan, Korea, with my former student Tsuzuki (Kyoto University), during 24-28, August, 2026

• Ohki gave a presentation about data-driven predictive control at IEEE CCTA 2026 in Vancouver, Canada, with Uchida (Kyoto University, Kashima lab), during 12-14, August, 2026

• Eighteen B3 students will enroll in this laboratory from September, 2026

• The website was launched in August 2026

• The lab was launched in April 2026

Our laboratory, the Quantum Related Technology Laboratory (QRTL), conducts research on classical and/or quantum dynamical systems, including quantum control and filtering theory, quantum state smoothing, controller synthesis, nonlinear filtering, model order reduction, statistical inference, and related applied mathematics topics. It seems diverse, but all themes are grounded in mathematics and physics from a control and estimation perspective. 

本研究室は，量子情報技術への応用を主軸とした，推定・制御の理論研究を行っています．その過程において，量子系の推定制御問題のみでなく，古典系の推定制御問題も扱っています．また，数理工学に基づいた様々な応用課題にも取り組みます．

• For undergrad students belonging to the Department of Applied Computer Engineering, Tokai University: Our common tools are basic math like linear algebra, calculus, probability, and statistics. If you would like to join us, I strongly recommend studying these subjects on your own and learning how to use them. GPA is not a criterion for selecting new lab members, but the curioucity for applied mathematics is quite important. 

B3以下の方：我々の研究室では，線形代数や微積分，確率統計といった基礎数学を学問のインフラとして利用します．当研究室を希望される人は，授業の範囲を超えてこれらを自習することを強くお勧めします（カリキュラムの都合上，授業では浅く狭くしかやれてません）．また，研究室のメンバーを選ぶ基準に GPA を優先していません．GPAよりも，上記科目をしっかり理解しそれらを応用することに興味を持っている人の方が好ましいです．興味のある人は，ぜひ話を聞きにきてください．

• For those joining as master's students or Ph. D. candidates: If you are interested in joining our lab as a graduate student, please contact Ohki before applying for the entrance exam. Especially for Ph.D. candidates, no one will be accepted without an appointment with Ohki in advance.
  修士課程，博士課程の指導を希望される方へ：出願前に一度研究の方向性の話を大木としてください．とくに博士課程を希望される場合，一度もディスカッションしたことない人は，受け入れません．

• For postdoc positions: If you are interested in joining our group, please contact Ohki anyway. We currently do not offer postdoc positions, but I can apply for funds to hire postdocs, or you can apply for JSPS's research fellowship programs.
