Fig. 2: The overall performance of BPQM compared with that of other related schemes.
From: Belief propagation with quantum messages for quantum-enhanced classical communications
a The overall block error rate of BPQM along with those of optimal joint Helstrom, symbol-by-symbol Helstrom followed by classical optimal block MAP, and symbol-by-symbol Helstrom followed by classical BP. b The same plot as a except that the error rates are also displayed in log scale.
