Outline of Final Research Achievements |
In this work, we aim to establish the quantum state conversion from photon-polarization to electron spin in semiconductor quantum dot and vise vars and to explore the novel concept of interconversion between photon polarization and spin. Then, we have achieved the verification of quantum state conversion from photon to electron spin, stable quantum dot under illumination, and highly efficient conversion. In addition, we have demonstrated the advanced semiconductor spin quantum technologies needed for the interconversion measurements, such as high-speed electron spin manipulation and high-fidelity and high-speed spin measurement. Moreover, we have observed electroluminescence from a planer pn junction, in which a quantum dot can be implemented, and a platform for the quantum state conversion from spin to photon.
