\n“Coupling to the resonators is done by placing a capacitor between the qubit and the resonator, at a point where the resonator electromagnetic field is greatest. For example, in IBM Quantum Experience devices, the resonators are implemented with “quarter wave” coplanar waveguides with maximal field at the signal-ground short at the waveguide end.”
