| Résumé | We present a microscopic theory of a lateral quantum dot molecule in a radialmagnetic field with a Greenberger-Horne-Zeilinger (GHZ) maximally entangled three particle ground state. The quantum dot molecule consists of three quantum dots with one electron spin each forming a central equilateral triangle. The antiferromagnetic spin-spin interaction is changed to the ferromagnetic interaction by additional doubly occupied quantum dots, one dot near each side of a triangle. The magnetic field is provided by micromagnets. The interaction among the electrons is described within an extended Hubbard Hamiltonian which is solved by using exact diagonalization techniques. The set of parameters is established for which the ground state of the molecule in a radial magnetic field is well approximated by a GHZ state. |
