Fig. 5: Effects of disorder.
From: Superconducting circuit protected by two-Cooper-pair tunneling
a Plot of the charge dispersion \(\epsilon\) of the qubit transition as a function of disorder parameters \(\delta\). Here, \({\delta }_{J}\), \({\delta }_{C}\), and \({\delta }_{L}\) correspond to disorder in the characteristic energy scales \({\epsilon }_{J}\), \({\epsilon }_{C}\), and \({\epsilon }_{L}\), respectively. Disorder in the area of the two Josephson junctions is represented by \({\delta }_{A}\). b Plot of the energy splitting \(\Delta E\) as a function of disorder parameters \(\delta\). The dashed lines and circles indicate the values of \({\delta }_{L}\) used for inductive disorder when computing coherence estimates.
