Research Abstract |
The electron spin in a semiconductor is one of the promising candidates for a quantum bit to be used in a quantum information devices and its optical responses are useful for realizing quantum repeaters. We theoretically analyzed the optical reposes of the electron spin in the semiconductor quantum structures. We proposed a quantum spin tomography which can completely identify the quantum nature of the electron spin. We also proposed a new scheme for photon-spin quantum state transfer based on the time-bin photon encoding which is suitable for a long distance quantum communication.
