Experimental demonstration of electrically driven coherent control of a single electron spin in a quantum dot. It established that local gate voltages, mediated by spin-orbit coupling, can replace direct oscillating magnetic control for single-spin manipulation.

Key Results

  • Demonstrates coherent single-spin control using an oscillating electric field from a local gate
  • Observes Rabi oscillations with 90-degree rotations as fast as about 55 ns
  • Interprets the electric-drive mechanism as spin-orbit-mediated EDSR in a semiconductor quantum dot
