a, b Illustrative single-particle and DQD energy levels for the (5,10), (6,9) and (7,8) charge states at B ≈ 0.4 T as a function of detuning ε. The red electrons and green (red) arrows indicate (the lack of) spin flip tunneling between the doublet D1/2− and quadruplet q3/2− ground states. For simplicity, the single-particle energy levels omit the two (four) lowest-lying energy levels of QDT1(QDB1). c–f Reflection coefficient of the resonator Γ as a function of f and ε for the (6,9)–(7,8) and (5,10)–(6,9) ICTs at B = 0 T and B = 0.4 T. g, h Resonance frequency and effective linewidth as a function of ε for ICTs (6,9)–(7,8) [red] and (5,10)–(6,9) [green] at B = 0.4 T determined by Lorentzian fits to the data in (e) and (f).
