"extremely energy-efficient optical switch that could replace electronic transistors in a new generation of computers manipulating photons rather than electrons... requires no cooling... 1 trillion operations per second... at room temperature! That said, there is a long way to go before such proof-of-principle demonstration is utilized in an all-optical co-processor"
