quantum mechanics

British computer researchers have produced a tiny microchip capable of using light rather than electricity to carry out calculations. It employs quantum mechanics to drastically cut the time taken for computations and could one day mean a ... substantially more secure Internet. University of Bristol researchers say the small size of the chip is the easiest change to demonstrate, but that this isn't its real innovation. And they are open about the fact that it won't replace standard computer processors. But the principle of what it does do is a genuine breakthrough. Exponentially Faster than ... (view more)
