Bottom line, why does the NSA want a quantum computer? To be able to decode data MUCH faster than we can today. There are trillions of bits being sent every day, you think they can keep up with the supercomputers of today?

What ever happened to optical computing? I remember there were big flame wars among the IV League nerds about which one was going to be better...

If you mean binary computing using photons instead of electrons, it's still progressing. That is the next step in the evolution of regular computers. Quantum computing is a different type of computing, with it's advantages and disadvantages. Think the difference between linux and windows. The each have their uses, and each has advantages and disadvantages. (Please don't start a linux/windows war in this thread. I am just using it as an example)

Isn't quantum encrypting where data is sent between two computers, and if the data is intercepted or read in any way by a third computer (even passively) the data itself is changed? I know with that they've actually got a working prototype
Some crazy stuff coming out in the next few years
Quantum Encryption vs Quantum Computing. I couldn't find much on optical computers vs quantum computers though

No, that ain't it, but I think I know what you are talking about. Some time ago I read about this really interesting study that suggested that finding results of some experiments would alter the results in following tests even if the experiment itself remained identical. If anyone has any links on that I would be more than happy to receive them
.<< Quantum Encryption vs Quantum Computing. I couldn't find much on optical computers vs quantum computers though
>>I think that quantum computer will remain in system meant for certain tasks (encryption, massive calculations etc.), whereas the generic computer will in the future move towards optical processing and/or clockless CPU's.
<< Not true. You're thinking about regular computers. Quantum computers use all kinds of weird quantum physics to break just about any encryption instantly. Even if you had 1024 bit encription it could be broken almost withough effort from a quantum computer. I can't explain it very well myself, but if you head to Slashdot and type quantum into the search box you'll come up with about 500 different articles that have been written, most with links to scientific journals that show exactly how quantum computers work when breaking encryption. I just hope that the NSA doesn't use it on everyday americans until we get quantum computers/quantum encryption on our desks.
Also: As it stands now, quantum computers will not be general purpose machines like a normal desktop is now. A quantum computer will be like an add-in card for todays computers. This may change in the future, but for right now they cannot design a general purpose machine, and specific job machines are still being worked on. >>
So that's why they don't need SETI@Home anymore, and have found cures for Cancer, AIDS and Bush' stupidity: They used a quantum computer to calculate all that stuff instantaneously! Was already wondering, thanks for clearing that up!

That does bring up an interesting point. Say the NSA did get a quantum computer....think they could have put it to use for cracking the human genome? What about those cancer things like SETI@Home, where you run that app on your computer and it supposedly figures out a cure for cancer? Couldn't they put something like that on there and get an answer/cure in seconds?
Edit: Eh, if that didn't make sense it's because I'm tired. Good night

i don't think so, UD simply finds "hits" - potential sources of a cure. the actual research is still done by scientists and their own computers.

There are no quantum computers available yet (at least officially). And it wouldn't be suitable for all tasks. The tasks that are suitable for quantum computers are:
Cryptography: perfectly secure communication.
Searching, especially algorithmic searching (Grover's algorithm).
Factorising large numbers very rapidly (Shor's algorithm).
Simulating quantum-mechanical systems efficiently.
