_Science_ v 287 21 Jan 2000 Has an article and report on using Rydberg states of atoms as *unary* representations for quantum state; this scheme does *not* require quantum entanglement but does use the quantum interference that makes quanta such interesting little fuzzy balls. The actual experiments involve zapping an ion with laser pulses, to set up the system and then read the result. The write pulses are phase controlled to program the system.
