The mind boggles when considering the implications of this tech.
It factors prime numbers better than anything else. It essentially would make obsolete all security codes.
I'm not really sure what this means. Are we talking about increasing processing power by a factor of 3? I guess what I'm asking is if this means that when I hit "popcorn" on my microwave will that now mean that popcorn just appears instead of me having to go get one of those bags and, if so, will it do away with the unpopped kernels?

Nah, it doesn't really work like that. For most computations a quantum computer isn't going to be any better than a digital computer. It's just that for certain types of computations quantum computing is much, MUCH better.
One of those types of computations is factoring prime numbers, which normal digital computers suck at. Most of the cryptographic security that we utilize in our day to day lives (think: email, online banking, logging in to DP...) relies on the difficulty of factoring prime numbers. Quantum computing can break through this security. Which is a big problem (or big advantage for whoever develops one first).
Maybe I'm missing something. Why is factoring a prime number so difficult? I always thought that what made a number "prime" was that its only factors were 1 and itself.
Sorry, factoring semi-prime numbers. A number that is the product of two primes.
Edit: and the key is that they have to be large. very large. Small numbers is no problem.

Yeah, I'm reading a little more on this. It seems that the current method of encryption involves multiplying two prime numbers. The result is another number that isn't prime but only has those two factors which then serve as the "key". So, for example, if you multiply 7 and 11 you get 77. You can then send someone a message tied to 77 but they would have to know that 7x11 is the only way to "unlock" that message. Obviously, that wouldn't be too difficult but sorting out the factors for 6697 would be a lot more work.
Also its worth noting that Qubits are in a state of superposition right up until the time they're observed or measured.
So they dont store or hold any information thats more complex than the average transistor once theyre observed. That is once their measured they're either a 1 or a 0
Its the intermediate steps during the computation that exploits the quantum properties of superposition and entanglement
