This is an example of quantum simulation, which is considered significantly easier to achieve than general quantum computing. Several quantum systems can be modeled with other, unrelated quantum systems, to solve the dynamics of those systems. The cannot unfortunately be used for general quantum gate operations that you hear about. And as usual, for QC stuff, I'll defer any real comments to Michael Nielsen, if he happens to see this submission.
