We demonstrate enhancement of the dispersive frequency shift in a coplanar waveguide resonator induced by a capacitively-coupled superconducting flux qubit in the straddling regime.
The magnitude of the observed shift, 80~MHz for the qubit-resonator detuning
of 5~GHz, is quantitatively explained by the generalized Rabi model which takes into account the contribution of the qubit higher energy levels.
By applying the enhanced dispersive shift to the qubit readout, we achieved 90$%$ contrast of the Rabi oscillations
which is mainly limited by the energy relaxation of the qubit. |
