5. The method of claim 1 wherein determining at least one characteristic of the first association graph via a quantum processor includes determining an independent set of the first association graph via the quantum processor, and wherein determining at least one characteristic of the second association graph via the quantum processor includes determining an independent set of the second association graph via the quantum processor.
5. The method of claim 1 wherein determining at least one characteristic of the first association graph via a quantum processor includes determining an independent set of the first association graph via the quantum processor, and wherein determining at least one characteristic of the second association graph via the quantum processor includes determining an independent set of the second association graph via the quantum processor. 7. The method of claim 5 , further comprising: returning an answer to the query from the digital processor based on ranking a size of the independent set of the second association graph with respect to a size of the independent set of the first association graph.
