Abstract :
We investigated the transmission properties of two coplanar waveguide resonators coupled with a flux qubit inductively. It is found that the transmission coefficients spectrum depends on not only the geometric resonator-resonator coupling constant, but also on the qubit-resonator coupling strength. Therefore, we can use the qubit to tune the coupling between the resonators in situ, realizing a quantum switch to generate entanglement of two resonators.
