Device structure a Optical image showing multiple CPW resonators frequency multiplexed to a common feedline (device B). Scale bar 1 mm. b Zoomed optical image of the capacitor plates that shunt the Josephson junction, with the gate, junction and contacts visible. Scale bar 100 μm. c SEM micrograph of a contacted boron nitride-graphene-boron nitride stack before fabrication of the gate. A magnetic field B|| can be applied parallel to the film along the length of the junction contacts using a 3-axis vector magnet. Scale bar 500 nm. d Cross sectional diagram showing the fully contacted and gated stack
