Hey guys check this out see what you think....a lot of it goes over my head but i haven't looked at it that closely. interesting stuff....kinda heavy thinking though.

http://www.cs.caltech.edu/~westside/quantum-intro.html

just imagine the speed.....equivalent to a supercomputer with ~10^150 processors......whoa

dude that shit is OLD

i think they have a faster speed then that now

yeah i kno. just didn't know if many of yall had ever heard of it. but they can't build the computers yet. well...only simple ones with a few switches. the switches they use are too fragile still for them to put millions of em on a chip. so no...they don't 'have' a faster speed than that. but they know how to get a faster speed.

I think there is some sort of comp between the world's uni's to build one because Melbourne Uni (In Australia) is building one and should have it finished in couple of years.

But the whole theory is kinda kool, computing done my protons of light, kinda fucked up eh !!

Quantum Cryptography is kinda interesting to though........................................UNCRACKABLE

uncrackable but from what I have read, it makes MITM attacks hard to detect

Well thats one large problem with it, since it is uncrackable, then no more things like intercepted messages and what not...........Since so far every type of crypto so far is breakable, the governments and such can read it and not let on that they know, with Quantum Cryptography that is just not possible.

Quantum physics has so many applications that it is unbelievable

It is not uncrackable it just uses very complicated algorithms that are un useable on the computers that we use today, since the processing power need is only achieved by using the power of quantum computing.

Well yeah at the standards of our technology it is uncrackable, like every good code, in the years to come we will have the computer power to crack it, but right now, not possible.........

I have a feeling the government knows a lot more than you think. I gurantee they have technology of the most advanced...

Wow I remember when this topic first started, did not think there would ever be more posted.

Im sure the government knows more than I think they do, but I do believe that the full capability of Quantum Computing is a bit beyond there reach also.........

Why are we talking about something that was news in 2000?

It was in the news in 2000, but the whole field of quantum computing is constantly being advanced. I just read an article in New Scientist talking about a new way to make quantum computers. Check out an article on it at http://www.sciencenews.org/20030222/bob11.asp . The processing power of a quantum computer is amazing. Think of a quantum computer to a supercomputer of today as how we would look at a supercomputer to an abacus, but even more powerful.

And supposedly quantum cryptography would be uncrackable, NTD; it's not just that we don't have the technology today. In order to to crack the code (or even just view it) you would have to observe the photons that are being sent. A cryptanalyst would not know the correct orientations at which to observe the photons so would not be able to crack it. There's more to it then that, and I don't profess to understand all of it myself, but theoretically quantum cryptography is entirely uncrackable.
