Outline of Final Research Achievements

Recent technical advances in manipulating quantum mechanical properties of electrons in solid-state devices suggest that the development of novel quantum technologies including quantum computation is feasible in near future. We aimed to use coherent electron waves known as edge states to unveil the influence of nuclear spin fluctuations against the quantum mechanical properties of electron spins. Then we realized selective spin injection to a quantum dot structure by using the edge states. We believe that our results will contribute to development of future quantum devices based on electron spins.
