The Problem
Hidden Subgroup Problem (HSP)
Given: A function <math>f</math> from a group <math>G</math> to a set <math>S</math>, <math>f:G \rightarrow S</math> which is promised to be constant and distinct on different left cosets of an unknown subgroup <math>H</math>:
Problem: Find the hidden subgroup <math>H</math> by returning a set of generators for <math>H</math>
An algorithm for the hidden subgroup problem is efficient if the algorithm runs in a time polynomial in the logarithm of the size of the group (for infinite groups the definition is more subtle.
