Abstract
A tunable coupler circuit includes a first transmission line, a second transmission line and a three-junction superconducting quantum interference device (SQUID) coupled between the first transmission line and the second transmission line. The three-junction SQUID includes a first Josephson Junction (JJ), a second JJ and a center JJ coupled in parallel to one another such that the first JJ and the center JJ forms a first loop and the second JJ and the center JJ forms a second loop. A resonant frequency of the tunable coupler circuit is tuned based on applying a first flux and a second flux to the first and second loops.
