The Dark Exciton in a Quantum Dot- A Novel Bright Qubit with Very Long Coherence Time

Abstract

We demonstrate for the first time that the quantum dot confined dark exciton is a natural, coherent and long-lived qubit. We optically "write" its spin state and successfully "read" its subsequent coherent evolution.
