D-Wave doesn't make real general-purpose quantum computers.  It's not a gate-oriented processor.  All it does is optimization.  This is useful as hell for machine learning and certain types of physics, but isn't very useful for cryptography.

Oh look, this thread again.

I'll also mention that if Bitcoin was ever "broken" by quantum computers, then banks, governments, corporations, the NSA and the internet in general would be at risk as they all use the same algorithms as Bitcoin to encrypt data, these algorithms were originally developed by the NSA and hundreds of millions of dollars worth of research has been done by people across the globe who were trying to break them and nobody has even come close in the past 20+ years, if they were ever broken lots of things could be easily decrypted and hackers would plunder and steal everything, Bitcoin would be the least of our worries it would be complete chaos.

If the hackers steal all the fiat money, the fiat money doesn't have any value.
Same goes for Bitcoin...
Not exactly.  Bitcoin is far, far harder to hack than bank security.

The hacking through quantum computers of bank security would of course, lead to a 'flight to safe havens..."

Bitcoin.

Minimum Effort/Maximum effect
You know an interesting thing that Bitcoin does? I don't think anyone has noticed but those useless computations that are done to secure the transactions they are hash collisions... finding by brute force the original hash of a transaction... in essence one day Bitcoin itself will crack the SHA256 algorithm at a 2x level... double SHA256 makes direct collision attacks brutally difficult so brute force has to be used... Bitcoin is brute forcing the algorithm and recording it.

which means that probably it's nobody's interest to break bitcoin?
happy days!

Duh.  Bigfoot uses one of these for his wristwatch.  That's how he's so easily avoided verifiable detection.

(any guess about its hashrate?):

Google has acquired a 512-bit quantum computer from a company called D-Wave. This computer will be deployed in a network of self-learning machines that will eventually take over the NSA and run the surveillance state.

Not sure about hashing with a general purpose quantum computer, but the D-Wave device seems not to be one.  It may outperform a classical computer for the optimisation problems it is built for, but AFAIK it can't run Shor's algorithm, for instance.

But who knows whether the NSA hasn't already that ability from a secret quantum computer anyway.
