Quantum Physics II : Interdisciplinary Fields between Physics and Engineering(Physics in Japan : The Past 100 Years and the Prospect)

Abstract

This article reviews the three research fields for which the quantum theory plays an essential role for its fundamental principles and experimental techniques. These fields are nuclear magnetic resonance (NMR), laser and quantum information. It is noted that the important concepts and basic principles of the three fields are very similar. The article emphasizes how a revolutionary idea of one field is successfully transferred to and flows in the other field.
