The ones and zeroes that propel the digital world — the fording of electrons across a transistor, or hard drives reliant on electrons' intrinsic spin — are getting packed into smaller and smaller spaces. The limit was thought to be set: no more than one bit of information could be encoded on an atom or electron. But now, researchers at Stanford University in Palo Alto, CA, have used another feature of the electron: its tendency to bounce probabilistically between different quantum states.
