Abstract: Top spin The GaAs double quantum dot is the classic spin qubit widely studied for its potential as information carrier in quantum computers. The discovery that electron spin flips in this system are governed by nuclear interactions, and slowed dramatically by a weak magnetic field, is promising in terms of the control and manipulation of spin-based memory.
