"Controlling Individual Spins in Semiconductors: Basic Physics and Applications to Quantum Information"
This talk will summarize progress in recent years, by our group and others, to control and read the state of individual spins in quantum dots defined by electrostatic gates in semiconductor heterostructures, nanowires, and carbon nanotubes. For one or two spins, this "technology" is now in hand, and work is now underway toward integrating larger numbers of spins while maintaining full control over the system. Surprising fundamental discoveries have accompanied technical progress, particularly concerning interactions between electrons and nuclear spins in the host material. Open problems and yet-unaccomplished technical challenges will be emphasized in this presentation.
