The quantum computer that many—us included—doubted would ever materialize showed up yesterday. However, I think it's fair to say that we're a little disappointed with what actually materialized. Sure, the hack thing to do is to praise its ability to solve Sudoku puzzles, but to me there's quite a difference between changing the way the world computes and solving a silly puzzle.

Another knock against D-Wave, the Canadian company that developed the computer, is that its computer is too small and underpowered to really do anything that quantum computers are supposed to do. And it looks like the cryptography community will have to continue to rely on current methods of cracking codes because D-Wave's baby can't be used to crack any encrypted communication. Overall, a disappointing launch, but not one that couldn't have been predicted.
