| Research Abstract |
This study aims the manipulation of nuclear spins via hyperfine interaction by all-optical methods based on our previous studies, which is essential for the realization of the applications such as quantum gate operation, quantum memory, and quantum media conversion. For this purpose, in this year, we developed the following two techniques. This technique allowed us to measure the nuclear field fluctuations of ~40 mT and to clarify their influences to electron and hole spin relaxations experimentally and theoretically.
