Figure 6From: The circuit quantum electrodynamical Josephson interferometerThe g ( 2 ) -function as given by equation ( 16 ) as a function ofJ/γandU/γin the in-phase strong driving regime forΩ/γ=5. The red color indicates a coherent field, where g ( 2 ) ≈1, whereas the blue area marks excitation-antibunching with g ( 2 ) <1.Back to article page
