Nah don't worry, this is old news and the dwave seems far too out there still.

Just remember this old infographhttp://i.imgur.com/vCkuFAY.jpeg

Uow, I've never seen this piece. So, is it certainly impossible that a new, disruptive processing technology is invented? I mean, that could process without the limitations we currently know?


That infographic is incorrect. Bitcoin has only 160 bits of security, since the hashes are only 160 bits. You don't need to match the private key, you need to match what it hashes to. Still, 160 bits of security is more than enough.
