Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem. The algorithm computes the two numbers that multiply together to form a given figure, and has until now required laboratory-sized optical computers.

This kind of factoring is the basis for a wide variety of encryption schemes. The work, reported in Science, is rudimentary but could easily be scaled up to handle more complex computing.
