Figure 5

Example of a THA against correlated IM and PM of Alice (Bob). The simulation is similar to that in Fig. 2 but now \(r \in \{\text{s,v,w,0}\}\). Moreover, we assume that Eve splits the joint back-reflected light into two parts by means of a 50:50 beamsplitter, one part is to learn information about the intensity settings and the other part is used to learn information about the basis choices.
