Supercomputers that consist of thousands of individual processors connected by miles of copper wires could one day fit into a laptop PC, according to IBM.
The company claims that a breakthrough by its scientists uses pulses of light through silicon, rather than electrical signals on wires, to send information between multiple cores or 'brains' on a chip.
This could lead to tiny 'supercomputers-on-a-chip' that expend the energy of a light bulb, compared with today's enormous machines that use enough energy to power hundreds of homes.
