Condensed Matter and Biological Physics Seminars

Spins in semiconductors have many desirable properties for quantum information processing. Recent key experimental demonstrations by several groups have considerably improved the prospects of physical implementation of a semiconductor-based processor. In this talk, I will highlight the recent progress of the UCLA group. The results of an experiment to manipulate single spin with microwave pulses and to detect its magnetic resonance and spin orientation will be reported. A demonstration of trapping, storing, and detecting single photoelectrons in a controllable electrostatic quantum dot will be presented. Our effort on the fabrication and characterization of long-coherent-time qubits on epitaxial SiGe heterostructures will also be described.
