Figure 7From: The circuit quantum electrodynamical Josephson interferometerThe g ( 2 ) -function as given by equation ( 16 ) as a function of φ andU/γforJ/γ=1andΩ/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
