FIG. 1.

Optimal success probability of the states given in Eq. (73), depending on the relative probability of the occurrence of (solid line). The dashed lines denote the success probability of single state detection (lower bound) and the dotted line corresponds to a simple upper bound. In brackets we denote the measurement types as defined in Sec. III B.

FIG. 2.

Optimal success probability depending on the relative probability of the occurrence of . (a) A “random” example. (b) An asymmetric example, cf. Eq. (74). In brackets we denote the measurement types as defined in Sec. III B. For details see text in Sec. VI C.
