Abstract

This paper discusses the behavior of single-electron states localized on quantum dots in an external magnetic field. Such states have a significant size of the electron cloud and can serve as a basis for implementing qubits with optical computation procedures. The orbital and spin “current” induced by a magnetic field in such states is calculated, along with the magnetic moments of these currents. It is shown that the magnetic susceptibility of the states of interest exceeds by several orders of magnitude the values that are characteristic of atomic physics, while the spin moment is determined only by the magnetic splitting factor of the semiconductor.
