Figure 4From: The circuit quantum electrodynamical Josephson interferometerThe coherent excitation number n 2 = | α 2 | 2 in the second transmission line resonator as a function of the nonlinearityU/γand the tunneling rateJ/γfor in-phase laser inputφ=0andΩ/γ=5. Stronger drives lead to even higher excitation numbers n 2 .Back to article page
