Does this mean that I need to throw away my 2048-bit RSA key? Is 4096 bit at all safer than 2048 from quantum computing?

- pudquick 13y agoNo. No speed up when compared to a classical machine (for much cheaper) emulating the exact same procedure: http://www.scottaaronson.com/blog/?p=1400 http://www.scottaaronson.com/blog/?p=1400

- beloch 13y agoThat depends... 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.
- i_am_dead 13y agoI'm willing to bet that N is a single digit.
