Optical images of coplanar waveguide (a) and lumped element resonators (b,c). Scale bars, 1 mm (a,b), 0.3 mm (c). The coplanar waveguides have resonance frequencies between 5.5 and 8.0 GHz with gaps ranging from 2 to 16 μm, corresponding to pMS between 1.5 × 10−3 and 2 × 10−4 and external coupling (Qc) around 1 million. The lumped elements have resonance frequencies between 4 and 5 GHz and gaps ranging from 2 to 100 μm, corresponding to pMS between 6 × 10−3 and 7 × 10−5 and Qc around 10 million.
