Light could make semiconductor computers a million times faster or even go quantum | University of Michigan News

More to come…

By treating these states as ordinary 1 and 0, it could be possible to create a new kind of “lightwave” computer with the million-times-faster clock speeds that Kira mentioned. The first challenge along this route will be to use a train of laser pulses to “flip” the pseudospins at will.
