If you read the article, they clearly mention that the problem they investigated is easily computable on a desktop PC. The problem has only has 40 possible states. You wouldn’t even notice the computation time of that on your cell phone. It would be calculated in a split second.

The point they make is a more theoretical one. They solve the problem in a way that the quantum computer can not “know” about these 40 possible states, which would mean that – at least theoretically – it would have to check all posible combinations. Solving it that way on a classical computer could indeed take the rest of your live to calculate :-)

That’s kind of the idea of using quantum compouters: beeing able to check all posible solutions (and non-solutions) very fast. But the actual problem solved in this case can easilly be solved – and very fast – by ordinary computers.

It’s getting pretty obvious that the rumors that they were running a scam are false.

They’re tackling an enormous engineering challenge, and I applaud them for their resilience.
