Magnetic resonance studies of semiconductor quantum dots for quantum information applications

This experimental project focuses on electron and nuclear spin physics in nanometer-sized semiconductor quantum dots. Semiconductor quantum dots are a promising hardware for the emerging quantum information technologies: the spin wavefunction of the electron can be used to store and process quantum information. The interaction of the electron spin with the spins of atomic nuclei is a major challenge on this way. The aim of this project is to develop a state-of-the-art quantum logic gate where electron spin is isolated from nuclear spins using magnetic resonance pulses. A variety of experimental techniques will be involved in this work: optical spectroscopy and microscopy, radiofrequency and microwave magnetic resonance spectroscopy, low temperature (liquid helium) experiments and high magnetic fields.
