It may well be that Quantum Computing will open up new ways of encrypting, but I can't see them. Everything I know encryption leaves me to believe that we are wide open. What little that I understand about the quantum microverse and quantum computing, leads me to think that anything quantum can *do*, it can *undo*. Although you may be able to encrypt huge keys, quantum allows you to try ALL the combinations on the lock at once, no matter how large. I know that practicality means you have to carve the key up so that you can go at it with the number of bit's you have at your disposal, but I don't see that as much of a barrier.
From what I understand about the NSA, "National Security" is paramount. Most of what I know is from reading "The Puzzle Palace", and he pretty much posits that NSA is *ALWAYS* a minimum 15 yrs ahead on tech, and usually 2 to 3 levels of tech above anything that we see. Assuming that, the fact that this is in the private sector leads me to believe that they're (NSA) on to bigger and better things. What that might be, I have no idea. Probably something odd discovered in the search for M/string-theory.
The CMPNet article scares me because they are talking practicality. Not 20 years off. Real world, many-bit devices. And NEC, the one with the solid state research, is a multinational corporation. Lucent, I hear is also in the game -- nearing practical results. I can't remember my source on the Lucent stuff, so take it with a grain of salt.
Sounds great! Does anyone else see the death of e-commerce in this?! I never did care much that the NSA probably had this stuff long ago, since I'm not a national security risk (at least I don't think I am). But large corporations having this stuff bothers me. Nothing was secure from the NSA (if you thought RSA wasn't crackable by them...dream on), but having nothing secure from corporations is a whole other problem.
And wait until some hacker cracks into Lucent's Quantum Computing Array, and breaks into your bank account.
