Abstract
A Josephson-coupled resonator amplifier is provided. The Josephson-coupled resonator amplifier includes a first and a second resonator, each formed from respective lumped-element capacitance and respective lumped-element inductance. The Josephson-coupled resonator amplifier further includes one or more Josephson junctions coupling the first resonator to the second resonator, whereby a superconducting loop is formed from at least the lumped-element inductance of the resonators and the one or more Josephson junctions.
