Outline and Purpose of the Course	As an example of high precision measurements using quantum phenomena, frequency standards, which is realized with the smallest uncertainty in all measurement quantities at present, are discussed. The principle and evaluation of frequency standards are explained.
Course Goals	The goal of this lecture is to understand that precision measurements are realized with combination of the best technologies and is based on physics.
Schedule and Contents	Introduction and principle of time measurement (1 time): Two principles of time measurement: Reproducibility postulate and dynamic model Fundamentals of atomic frequency standards (2.5 times): Atomic states, its energy shifts, high-resolution spectroscopy and high-sensitive detection Cesium frequency standard and atom interferometer (2.5 times): Principle of Ramsey resonance and its interpretation as atom interferometer Specification of frequency standards: evaluation methods and theoretical limit (2 times): Fundamentals of evaluation of frequency stability with Allan variance, and theoretical limit of frequency stability Noise (2 times): Incoherent signals and shot noise Relativistic theory and time (3 times): Impact of special and general relativistic theory on time measurement Others (1 time) If we have time, the frequency noises of masers and lasers, and other subjects will be lectured. Evaluation of understanding (1 time)
Evaluation Methods and Policy	Report(two times, at the first lecture and the after all lectures)
Course Requirements	Fundamentals of physics (quantum physics, in particular) and electric circuits including linear system. The level which average graduate students of electric and electronic science and technology acquire is sufficient.
Study outside of Class (preparation and review)	In case you need.
Textbooks	Textbooks/References	Some materials will be provided in the case we need.
References, etc.	The Measurement of Time, C. Audoin and B. Guinot, (Cambridge University Press), ISBN:0521003970, This is a nice book for this topic. I recommend anyone who are interested in this topic to buy one. Basics of Electronics Circuit (in Japanese), Masao Kitano, (Reimei), This is a textbook used on the lectuer "Electronics" in fuclty. I will use this on the topic "Noise".
