Is there a limit to how fast and how powerful computers can be? According to Moore’s Law, the power and speed of devices doubles every two years. But as this occurs we are getting close to the physical limit that silicon transistors can work at (at the moment they are just 70 silicon atoms wide).
Well there my be no limit on computer power, if we switch from moving elections around (which is what current transistors do), to moving photons (i.e. light). One advantage of this is that photons move 20 times faster than electrons, as well as being ‘smaller’.
