Both methods for single spin control are orders of magnitude faster than conventional electron spin resonance and allow investigations of single spin coherence in the presence of fluctuating nuclear and spin-orbit fields.

By shifting the orbital position of the electronic wavefunction at gigahertz frequencies, we can control the orientation of a single electron spin and measure the full g-tensor, which exhibits a large anisotropy due to spin-orbit interactions.
The second method utilizes the strong spin-orbit coupling of InAs. The first method is based on quantum interference and implements spin-interferometry on a chip. In this talk I will describe recent progress in the field, focusing on two new methods for single spin control that have been developed by my group at Princeton. We demonstrated coherent control of a quantum two-level system. At the time of the proposal, it was not possible to trap a single electron in a device and measure its spin, let alone demonstrate control of quantum coherence.

Over ten years ago, Daniel Loss and David DiVincenzo proposed using the spin of a single electron as a quantum bit.
