Driven coherent oscillations of a single electron spin in a quantum dot
... The next major achievement was the observation of the coherent exchange of two electron spins in a double dot system, controlled by fast electrical switching of the tunnel coupling between the two quantum dots14. Finally, free evolution of a single electron spin about a static magnetic field (Larmor ...
