ELECTRONIC DEVICE WITH SPIN QUBITS

Abstract

The invention relates to an electronic device comprising: - first and second quantum dots (QD1, QD2) arranged along an x-direction, - first and second control grids (41, 42) associated with said quantum dots, - a magnet (20) configured to generate two opposite spin states at each of the first and second quantum dots. Advantageously, the magnet comprises first and second magnetic domains (21, 22) distributed along the x-direction and separated by a domain wall (30). These magnetic domains exhibit first and second magnetizations (A1, A2) of opposite directions along the x-direction. The first and second quantum dots thus perceive first and second magnetic field gradients. The invention also relates to a method for implementing and initializing such a device.
