Optical Spin Initialization and Non-Destructive Measurement in a Quantum Dot Molecule
Danny Kim, Sophia E. Economou, Stefan C. Badescu +5
The spin of an electron in a self-assembled InAs/GaAs quantum dot molecule is optically prepared and measured through the trion triplet states. A longitudinal magnetic field is use…

Optically induced spin gates in coupled quantum dots using the electron-hole exchange interaction
Sophia E. Economou, T. L. Reinecke
We propose a fast optically induced two-qubit \textsc{c-phase} gate between two resident spins in a pair of coupled quantum dots. An excited bound state which extends over the two…
