Electron Traps That Compute

Physicists have used a semiconductor material to create superimposed quantum dots that "trap" single electrons. Not only can these dots be studied with lasers, their energy can be influenced as well.

Another point: the state of one of the dots governs that of the other above it. This has taken the researchers another step closer to quantum computers.
