  1. n: size of the input string, M : total number of wavelength-composite pulses sent from Alice/Bob to Charlie. μA and μB : total number of photons that are sent to Charlie by Alice and Bob respectively, C1,E : total counts recorded by detector D1 when Alice and Bob have same inputs, C1,D : total counts recorded by detector D1 when Alice and Bob have different inputs, C1,th : threshold value of the total counts at detector D1, Perror : error probability, Q : amount of information communicated in our experiment. It is calculated as the equivalent number of qubits. γC : ratio of the amount of communication in the best-known classical fingerprinting protocol25 to Q (\(32\sqrt{n}/Q\)); γQ : ratio of the amount of communication in the original coherent fingerprinting protocol29 to Q.
