From: Generalized sequential state discrimination for multiparty QKD and its optical implementation
Plots of the success probability of the sequential state discrimination of the coherent states, when four receivers exist. The solid black line (dashed black line) shows the optimal success probability when three receivers discriminate two pure states of Alice (one out of two pure states of Alice). In (a), we use \({q}_{1}={q}_{2}=0.5\) and in (b), we use \({q}_{1}=0.4,{q}_{2}=0.6\).
