Abstract

A degenerate string is a sequence of sets of characters. A generalized degenerate (GD) string extends this notion to the sequence of sets of strings, where strings of the same set are of equal length. Finding an exact match for a pattern string inside a GD string can be done in O(mn+N) time (Ascone et al., WABI 2024), where m is the pattern length, n is the number of strings and N the total length of strings constituting the GD string. We modify this algorithm to work under a quantum model of computation, achieving running time {O}\(sqrt{mnN}\).
