Instead of having 2 values for a bit we would have 3 for qbits. 4 bits can contain 16 values (0 thru 15) when all bits are on. If 4 qbits are on, then in a base 3 system you would have 81 values. It grows exponentially in power for every qbit column added. I can see where that would be quite a bit (pun intended) more powerful. Imagine if they could do that with a hard drive somehow. If they get this down, it's going to make the best pc's of today look like cheap toys. Still not sure I'm wrapping my head around that super postion stuff though. What's the max number of simultaneous states? The video shows on, off or both. Can there be more that that. Like 5 states at once?
@softwaregeek: The max number of states is 2 for 1 qbit, 4 for 2, 8 for 3, etc.... Every time you add a qbit the number of simultaneous states doubles. Like the guy in the reality check video say iirc though, they are really good at specific things so we'll likely have a mix of quantum chips and regular chips.

I understood it as the max number of states for a bit is off or on (0 or 1) which is what we have now. For a qbit, the max number of states is at least 3. Off (0), On (1), or both (which would be off and on at the same time) (*). Having two states at the same time would be a 3rd value. Anyway, good post. Thanks for sharing.
I like this take on QC the best, mostly because the individual in it is extremely passionate, but quite obviously is going out of his way not to over-promise or sell people on possibilities that might never come about.

I thought it was hillarious when he dressed up in his big red ball :) Thanks for that.
The "What can Quantum Computers Do" incorrectly stated that 8 bits could hold a value 0 thru 256. It's actually 0 thru 255 for a total of 256 numbers. just as 0 thru 10 is 11 numbers. Just an observation.

When I see posts like this, I think to myself "mental midgets".
Yeah. But don't judge them. Some people have different priorities. Some peopel are stupid, but physically strong. Some people are physically weak, but intelligent. It doesn't really make anyone more valid.
OT: **** yeah this is very interesting. Seems like it will take a very long time to get there though (as he said; 20 or 30 years).

you just had to suck the joy out my trolling post...lol

After looking over the first few chapters of this: http://www.cl.cam.ac.uk/teaching/0809/QuantComp/notes.pdf
It seems like a qubit is made up of a superposition of two states. It is really one state, but a 2-dimensional one described as a vector. The number of super-imposed calculations (which I was talking about by mistake in my original post) that can be carried out is equal to 2^n, where n is the number of qubits you can have.
Weird stuff. Anyone know any good books for getting into quantum computing more? Now i need to get back to work, this stuff is distracting..... heh
Quantum computing is the future of everything. Traditional transistor processors are going to reach a plateau of power at some point in the next 5-10 years, and won't be capable of improving further... so the only way to improve power is to make the jump to quantum. I don't particularly understand the process itself, but the gains are astronomical even for the most basic type.

Hopefully not breaking some rule, but if you like the style check him out. He guy is pretty neat. People ragged hard on him because of his giddiness to teach early on, but these days he is just a goof ball that wants you to know everything he thinks is neat.

Already subbed, so I can check him out later. Being goofy takes courage too and he seems very informative.
honestly next 10 years in computing is going to change beyond belief, possible neurosynpatic chips in heavy use and quantum computing is starting to hit the ground, i believe we will be making multi layer computers in the future ala a computer having both a neurosynaptic processor on board and a vonn neumann CPU onboard tagged with a a super power GPU and vice versa
