| Research Abstract |
The control of nuclear spins in semiconductor nanostructure has been demonstrated by magneto-optical spectroscopy. The optically created nuclear field was up to 5 T and one of candidate for driving forces of quantum information processing due to the locality and nonlinearity. The polarization measurements and first order photon correlation measurements were performed to investigate optical properties of the the quantum ring and nanowire quantum dot structures in the view point of the single and entangled photon sources.
