Figure 3. φ1 = π/2 and φ2 = 3π/2. (a) ωg = ωr, the transmission coefficient with different κr/κg. The blue and red curve correspond to κr/κg = 1 and κr/κg = 4, respectively. (b) κr/κg = 1, the resonator is tuning across the giant atom. (c) κr/κg = 4, the resonator is tuning across the giant atom. (d) When the components are papered in the entangled state $\left|{\psi }_{+}\right\rangle =(\left|e0\right\rangle +{{\rm{e}}}^{{\rm{i}}\pi /2}\left|g1\right\rangle )/\sqrt{2}$, the interference effect leads the photon propagates towards right (blue arrow).
