A composite figure: a false-coloured scanning electron micrograph of an 18-qubit gate-defined quantum-dot array (100 nm scale bar), plus charge-stability maps and calibration plots. It is Fig. 1 of "Simultaneous operation of an 18-qubit modular array in germanium" by J.J. Dijkema, N.W. Hendrickx and colleagues. Each spin qubit sits under a blue plunger gate, with red barrier gates tuning the coupling between neighbours; the arrowed panels show the tune-up chain, from charge stability and Pauli spin blockade to Rabi and two-qubit spectroscopy.“Fig. 1 — Fig. 1: Device and measurement protocol of the 18-qubit modular array. a, False-colored scanning electron microscope image of the 18-qubit device.
