Quantum computing and Sudoku, part II
Following up on yesterday's post, there is a video available on YouTube that does appear to show the D-Wave quantum computer solving a Sudoku puzzle more or less instantaneously.



This still doesn't tell us very much, though. As the AP reported this morning, no one can be certain if the computer in question is actually making quantum calculations. And as The Browser's excellent readers have pointed out in comments to the previous item, you don't need a quantum computer for this relatively simple task. (Kevin of Baltimore: thanks for the code! But I don't think we can publish it here.) So it's still unclear why Scientific American and other outlets are touting this as evidence of a breakthrough.
