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.
