Capacitive coupling of coherent quantum phase slip qubits to a resonator

We demonstrate capacitive coupling of coherent quantum phase slip (CQPS) flux qubits to a resonator patterned on a highly disordered TiN film. We are able to detect and characterise CQPS flux qubits with linewidths down to Δ ω = 12 ± 1 MHz on several resonator modes, and show that, unlike inductive...
