Course description and aims

【This lecture will be given in Japanese.】
In this lecture, we first learn classical feedback control for a precision measurement that is quite often required in Physics experiments. We then learn a difference between a classical control and quantum control.

Student learning outcomes

Through this lecture, students will learn
(1) a meaning of trapping and cooling of an object
(2) a difference of classical and quantum controls.


feedback control, quantum limit, harmonic oscillator

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The lecturer will use both blackboards and powerpoint slides.
The lecture will be given in Japanese for this year.
