The largest fully programmable optical processor to date has been unveiled by researchers at the Massachusetts Institute of Technology and Elenion Technologies. The device, which is made up of a mesh of 88 beam splitters that can be programmed on microsecond timescales, could be used to study a large range of quantum transport regimes in great detail and help in the development of novel nanoelectronics and memories…..
