High-speed electrical control of a solid-state photonic quantum interface

We demonstrate high-fidelity transfer of the polarisation of a photon into the spin-state of an electron-hole pair. Spins are then electrically manipulated on sub-nanosecond timescales and near-unity phase-shift and spin-flip gate operations are demonstrated.
