    Can't be too hard on it as this is like a normal computer in the 1940's.

    D-Wave uses quantum method to solve protein folding problem
    August 21, 2012

(Phys.org) -- While there has been some skepticism as to whether the Canadian company D-Wave’s quantum computing system, the D-Wave One, truly involves quantum computing, the company is intent on proving that the system is both a quantum device as well as a useful one. In a new study, D-Wave CEO Geordie Rose and other D-Wave researchers have teamed up with Harvard quantum physicist Al├ín Aspuru-Guzik and post-doc Alejandro Perdomo-Ortiz to demonstrate that the D-Wave One system can solve the challenging task of finding the lowest-energy configuration of a folded protein.

    The study, “Finding low-energy conformations of lattice protein models by quantum annealing,” is published in a recent issue of Nature’s Scientific Reports. The computer used quantum annealing to find the lowest-energy protein configuration by solving for the configuration as an optimization problem, where the optimal state was the lowest-energy state. Proteins can be folded in a large number of ways because they’re made up of many chains of amino acids. Yet somehow, proteins almost always manage to fold themselves in the correct configuration (when they don’t fold correctly, they can cause misfolded-protein diseases such as Alzheimer's, Huntington's, and Parkinson's). Scientists think that proteins fold themselves correctly because the correct configuration is also the state of lowest energy, the state at which the protein becomes stable.
