This project is focused on probing the spin dynamics of electrons localized within semiconductor quantum dot nanostructures. When subject to an external magnetic field, the spin degree of such isolated electrons represents one of the most promising routes towards the realization of a q- bit, the fundamental hardware required to build a quantum computer. A broad range of spatially resolved optical spectroscopy techniques will be combined to ascertain the potential for using charged quantum dot nanostructures as spin qubits. Specific scientific goals of the project are as follows:
- Selective spin initialization of few-electron QD and QD-molecule systems.
- Investigations of environmental factors influencing the spin coherence time.
- Demonstration of high-fidelity all optical single spin measurements.
- Development of new techniques for electrical single spin readout.
