Abstract (in Japanese) (See Japanese page) 
(in English) Superconductors are very sensitive to electromagnetic waves and they enable to detect signals at quantum limits. On the other hand, superconductive devices are easily affected by small charges and magnetic flux nearby. Noises in amorphous materials under microwave irradiations were studied for years and they can be explained by tunneling model in two-level systems. We survey the two-level fluctuations in superconductors and show about the mutual interaction between
two-level fluctuators.
