''The 26-millimetre-long chip was designed and built using standard fabrication processes by Jeremy O'Brien, Jonathan Matthews and Alberto Politi at the University of Bristol, UK. It can run Shor's algorithm in cut-down form – confirming that 3 and 5 multiply to form 15, which is the simplest possible demonstration.

Unlike the silicon chips inside conventional computers, the Bristol team's chip uses light rather than electricity. Light-transmitting silica on a silicon wafer guides photons with entangled quantum properties around, an approach first demonstrated by the same team last year.'' [source]
