IBM scientists have announced a breakthrough that could lead to a new generation of supercomputers that squeeze the processing power of today’s giants into the form factor of a laptop. The research is based on the use of a light pulses sent through silicon instead of electrical signals on wires which make up conventional computer chips and also promises incredibly energy efficient processors that would expend only the energy of a light bulb to achieve what current supercomputers do with enough power to run hundreds of homes.
