Abstract
The present invention relates to an inductive dipole element for a superconducting microwave quantum circuit. The dipole element comprises a DC-SQUID formed by a pair of Josephson junctions shunted by an inductance, wherein the Josephson junctions have equal energy, and the Josephson junctions and the inductance are arranged such that each of the junctions forms a loop with the inductance. The two loops are asymmetrically threaded with external magnetic DC fluxes φand φ, respectively, such that φ=π and φ=0, wherein parametric pumping is enabled by modulating the total flux φ=φ+φthreading the dipole element, thereby allowing even-wave mixing between modes that participate in the dipole element with no Kerr-like interactions.
