This talk will review recent progress in the control of single electron spins in quantum dots, with an eye toward someday building a quantum computer based on electron spin as a holder of quantum information. The main technical challenge, which is preserving the long coherence time, raises an important physics question: why is it so hard. We report on recent experiments by our group and others on spin quantum bits in GaAs and other materials, including carbon nanotubes and Si nanowires.
Coffee and cookies before the presentation at 3:15 pm, and refreshments after the presentation will both be served in Room 128.
