Deterministic Writing and Control of the Dark Exciton Spin Using Single Short Optical Pulses

Deterministic Writing and Control of the Dark Exciton Spin Using Single Short Optical Pulses

We demonstrate that the quantum dot-confined dark exciton forms a long-lived integer spin solid-state qubit that can be deterministically on-demand initiated in a pure state by one optical pulse. Moreover, we show that this qubit can be fully controlled using short optical pulses, which are several...
