Figure 3From: Tunable coupling of transmission-line microwave resonators mediated by an rf SQUID Uncalibrated cross-transmission from resonator A to resonator B as a function of the applied flux. Near \(\Phi_{\mathrm{ext}}=0.468 \Phi_{\mathrm{0}}\) and \(\Phi_{\mathrm{ext}}=0.532 \Phi_{0}\) (white arrows), the resonators decouple and signal transmission is blocked. The red arrows mark the flux values, for which transmission vs. frequency cuts are shown in Figure 4.Back to article page
