Figure 4From: Tunable coupling of transmission-line microwave resonators mediated by an rf SQUID Uncalibrated through- (red) and cross-measurements (blue), obtained for three different flux values. (a) \(\Phi_{\mathrm{ext}}= \Phi_{0}/2\), \(|g|\gg|\Delta|\): strongly coupled regime, only the mode \(\Omega_{1}\) is shown. (b) \(\Phi_{\mathrm{ext}}=0.468\Phi_{0}/2\), \(|g|\simeq 0\): decoupling point. (c) \(\Phi_{\mathrm{ext}}=0.439\Phi_{0}/2\), \(|g| \simeq\Delta\).Back to article page
