Microchips and photonchips

Earlier this week, Google celebrated the co-creator of the first microchip with one of their Google Doodles. A microchip is defined by Wikipedia as "an electronic circuit manufactured by the patterned diffusion of trace elements into the surface of a thin substrate of semiconductor material."




I'll be honest, I read that a few times, and all I got was tiny thingamajig with some tiny conductor thingies that makes computers and the like work. Computers, cell phones, and other digital products couldn't work without them. Various microchip-esque ideas came and went between 1945 and 1958, when the first working microchip was created by Jack Kilby. They have come quite a ways since then. Moore's Law states that (in the long term) the number of circuits that can be inexpensively fit on a microchip of equal size doubles every two years.



Now, a new advance may put Moore's Law in the past. A new chip is in development which manipulates individual photons of light, guiding them and also containing and initiating their interactions. These tiny pathways on a silicon chip represent a huge step towards a quantum computer. Is anyone else thinking about the wonders of tomorrow-land?
