Quantal and Classical Coherence and Correlation

Takayoshi Kobayashi is a professor emeritus at the University of Tokyo, from which he graduated with bachelor’s, master’s, and doctorate degrees. He joined the Institute of Physical and Chemical Research (Riken), and from 1977 to 1979, he was a temporary member of the technical staff at Bell Laboratories. In 1980, he joined the Department of Physics at the University of Tokyo as an associate professor and was promoted to full professor in 1994. In March 2006, he retired from the university and moved to the Department of Applied Physics and Chemistry at the University of Electro‑Communications in Tokyo. He was then appointed as Chair Professor and Director of the National Chiao‑Tung University in 2006, which became the National Yang‑Ming Chiao‑Tung University in 2021. His research interests include quantum electronics, laser physics, femtosecond spectroscopy, ultrafast nonlinear optics, quantum optics, chemical physics, and quantum information science and technology.
