You want to know what this D-Wave technology represents? A start.
Yes and no.
Yes, D-Wave technology represents the first practical step in one possible direction for building practical quantum computers.
No, in that it is an insane hype machine. How many pieces have you seen which claims that D-Wave is working on solving NP-complete problems efficiently, something which pretty much everyone believes quantum computers are incapable of doing? If D-Wave can't live up to the hype, it may ruin quantum computing for everyone, and that would be a bad thing.
My mother (who has spent a lot of her life on committees of various kinds) taught me from a young age that the problem isn't often what is done, but the way it's done. D-Wave embodies this principle.
