Here's quantum computing at its finest. If you guys haven't heard of
schrodinger's cat , its about this guy schrodinger who came up with this experiment in which a cat is put in the box and stuff is done to it and you don't know if it is alive or dead until you open the box. So till that point in time when you open the box, the cat may be alive and dead at any point before that. Its really hard to simplify that cat shit.
well, anyways, thats essentially what quantum computing is about. Playing with uncertainess. Computers so far had transistors that worked as a specific 1 or a 0. Well not any more!

From the article:
"With the right set-up, the theory suggested, the computer would sometimes get an answer out of the computer even though the program did not run. And now researchers from the University of Illinois at Urbana-Champaign have improved on the original design and built a non-running quantum computer that really works."
This is an awesome beginner's read to understand this shite. Read :
