From: Hamiltonian of a flux qubit-LC oscillator circuit in the deep–strong-coupling regime
(a) The inductances of the LC oscillator \(L_{LC}\), (b) the inductance of the flux qubit \(L_{FQ}\), and (c) the inverse inductance of \(\hat{\mathcal {H}}_{12}\), \(1/L_{12}\) obtained by Eqs. (9), (10), and (3) (solid lines) are plotted as functions of \(L_c\) together with their counterparts in the separate treatment (dotted lines) on condition that the inductance sums are kept constant at \(L_c + L_1=800\) pH and \(L_c + L_2=2050\) pH.
