Quantum Computing

[Straha]

Could someone explain to me how Quantum Computers are supposed to work? I have heard of them and read a couple articles on them but still have no clue. Thanks in advance.

Magic. No, seriously, quantum physics is the closest thign to magic ever.

There are three Quantum states. Up, Down, and something else. (I think) Binary is just 0s and 1s, but with QCs, you can get a particle that functions as both at the same time.

You want the reader's digest version, or the longwinded version?

The reader's digest version is this:

In normal computers, a bit is a Binary Digit, either 1 or 0 (on or off, that sort of thing). In Quantum Computing, a qubit (quantum bit) is capable of being both on and off at the same time. This means that while a normal computer would be trying potentially thousand of passes to solve, a Quantum Computer could do the same job in just a few passes (sometimes even just one).

The longer version takes a considerable amount of time and text to explain, but google should be able to help in that regard.

I think I got that down, lets go to the more advance explanation.
