Abstract
A device comprises a Josephson junction traveling-wave parametric circuit. The Josephson junction traveling-wave parametric circuit comprises unit cells which are coupled in series to form a transmission line between an input port and an output port. Each unit cell comprises a series Josephson junction, and a capacitor shunted to ground. An impedance of the unit cells is varied along the transmission line to match an input impedance at the input port to an output impedance at the output port, wherein the input impedance and the output impedance are dissimilar.
