Just been reading up a bit on this topic and I was curious to know what you guys know about it.

What would quantom computers do for the world and what purpose would the average consumer have for it? What would it do for gaming?

major advances in cryptography, simulations of weather systems, protein folding and other simulations of the natural world, and possibly advances in natural language recognition and translation.

Probably no real practical uses for end user devices in the next 20 years.

And probably nothing for gaming in the foreseeable future, not until we start getting to the holodeck/matrix level of fully simulated virtual worlds anyway.

Faster porn in 4320p times one hundred.

It would give us pixar graphics at a bajillion frames per second that's what it'd do for us.

What a mere understatement. 

Can someone give a link describing quantum computing in layman's terms? Or could someone here describe it for me?

Awesome, thanks!

Quantum computing is so far away we'll be old and gray before we see what it can really do. It's going to be pointless for consumers, not to mention the cost would be more that 99 percent of the population could afford. But the idea behind what they could be is pretty scary, if you stop to think about it. Skynet? Maybe, more government control, definitely. Quantum physic it's self opens the doors to what we think about today as impossible. Teleportation, folding space and time, Extra dimensions, can you imagine they could be hundreds of copies of your self, unaware of each other? Head explodes!

I'm not too amazed by it. I absolutely love the science behind it but for actual use it is not that impressive. Sure certain things like calculating the minimum amount of moves to solve a rubik's cube could be calculated instantly but other problems can be solved faster with basic transistors. Computers in the future will be super powerful but power does not equal sentience like many people think, and quantum computers will have a gradual step up from binary.
