Ultrastrong tunable coupler between superconducting LC resonators
Takafumi Miyanaga, Akiyoshi Tomonaga, Hikaru Ito +2
We investigate the ultrastrong tunable coupler for coupling of superconducting resonators. Obtained coupling constant exceeds 1 GHz, and the wide range tunability is achieved both…

Quasiparticle tunneling and 1/f charge noise in ultrastrongly coupled superconducting qubit and resonator
Akiyoshi Tomonaga, Hiroto Mukai, Fumiki Yoshihara +1
We report an experimentally observed anomalous doubly split spectrum and its split-width fluctuation in an ultrastrongly coupled superconducting qubit and resonator. From an analys…
