> With the correct materials, in theory you could slow down light enough to control its flow through a circuit with a series of nano reflective materials and its overall carrying capacity for speed of information would far outmatch electrons which require a medium to travel through which ultimately renders it many times slower than the speed of light depending on the properties of the material. That's an extremely load-bearing "in theory".
