| Outline of Final Research Achievements |
We detected and controlled correlated states of electrons in units of a single electron, using quantum electron optics, where quantum states of propagating electrons are manipulated. Employing a single localized electron spin confined in a quantum dot embedded in an interferometer, we revealed microscopic natures and spatial extension of the Kondo state, where the localized spin is screened by its surrounding conducting electrons. We also developed technologies for transferring a single electron spin through a depleted channel and for splitting spatially a quantum mechanically correlated electron pair, to generated a non-local spin entangled state.
