Quantum computer solves problem, without running

If I had stayed in school, maybe I would understand this fully -- what I do understand however, is that quantum mechanics is really, really weird. Researchers at the University of Illinois at Urbana-Champaign have managed to combine quantum computation with quantum interrogation to produce a result from an algorithm, without ever running the algorithm. The researchers demonstrated what is known as counterfactual computation -- inferring information about an answer -- by exploiting the nature of quantum interrogation using a photon based quantum computer. What this result point to is the potential infer answers from an algorithm without ever executing the algorithm.
