| Research Abstract |
Precise control of quantum mechanical properties of individual electrons may offer new concepts of solid-sate quantum physics as well as applications to information processing. We have used semiconductor quantum dots and quantum wires to experimentally study the fundamental physics. We have realized quantum bits and logic gates with single electron spins in quantum dots, electrical control of the spin effect including superconducting effect, and electrical control of electron wave propagating in quantum wires. These are all first experimental demonstrations linked to the new concepts described above. These studies will largely promote science and technology of quantum coherence control.
