Fig. 2: Various single-electron configurations within the array.
From: Single-electron operations in a foundry-fabricated array of quantum dots
a–c Three different double-dot configurations, controlled by compensated voltages \({V}_{{{1,2,3}}}^{\mathrm{c}}\). Numbers indicate the occupation of the three qubit dots (each red dot represents one electron). d Similar to c, but with \({V}_{{{2}}}^{\mathrm{c}}\) fixed at a larger positive voltage, revealing the triple-dot ground-state region. In a–d the top gate is fixed at 6 V.
