Figure 4
Entanglement entropy and visibilities of one- and two-particle interference patterns of arrival time, as functions of \(\eta\). Panel (a) show the entanglement entropy calculated from the initial wave function given by Eq. (6). Panel (b) shows the one-particle visibility V, the two-particle visibility W, and their squared sum \(V^2+W^2\), represented by blue square, black diamond, and gray circle markers, respectively. The setup parameters and initial conditions are the same as in Fig. 3, and the error bars are estimated from the counting statistics.
