Component for initializing a quantum dot

An electronic component (10), which is formed by a semiconductor component or a semiconductor-like structure having gate electrode assemblies (16, 18), for initializing a quantum mechanical state of a qubit, comprising:

• a substrate (12) with a two-dimensional electron gas or electron hole gas;
• electrical contacts for connecting the gate electrode assemblies (16, 18) to voltage sources;
• gate electrode assemblies (16, 18) having gate electrodes (20, 22, 36, 38, 40, 42, 44), which are arranged on a surface (14) of the electronic component (10), for producing potential wells (30, 34) in the substrate (12);
• a reservoir (49), which is provided as a donor of charge carriers (48);
• the gate electrodes (20, 22, 36, 38, 40, 42, 44) of the gate electrode assemblies (16, 18) having parallel electrode fingers (26, 28, 37, 39, 41, 43, 45), wherein
• the gate electrodes (36, 38, 40, 42, 44) of a first gate electrode assembly (18) in the substrate (12) form a static double potential well (34), or the gate electrodes (36, 40, 42) of a first gate electrode assembly (18) in the substrate (12) form a static potential well (70), in which the charge carriers (48) are introduced from the reservoir (49) into quantum dots (50, 54);
• the gate electrodes (20, 22) of a second gate electrode assembly (16) form a movable potential well (30) in the substrate (12), wherein a charge carrier (50) with its quantum mechanical state can be transported with this potential well (30);
• means for transferring two charge carriers (48) from the reservoir (49) into the static potential well (34, 46, 70);
• a stimulator (51) for orienting or splitting the quantum dots (48, 50, 54);
• and
• means for transferring a charge carrier from the static potential well (34, 52, 70) into the movable potential well (30).
