## Quantum computer slips onto chips

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.
