The D-Wave processor probably isn't useful for cracking it. However, if you send RSA encrypted data, copies can be made of the encrypted data and cracked at a later date when better facilities or algorithms become available. If you wish to send a message that would make the NSA want to hunt you down and kill you if they decrypt it N years from now (and you plan to live >N years), you should probably be more careful. I don't think we have a good idea of what N is. It's probably pretty big, but it might not be.
