From The Telegraph:
An 'optical computer' which uses light particles rather than traditional circuitry has performed the first ever calculation, as scientists hope it could pave the way for a computer smaller and faster than anything seen before.
Scientists have hailed the step, despite the calculation taking longer than a schoolchild.
The optical quantum chip uses single particles of "whizzing" light which could eventually pave the wave for a "super-powerful quantum computer".
