a The qubit array mounted in its package by 107 wirebonds and surrounded by the package PCB (TMM10). Labels for each transmon qubit are in Fig. 2a. b Micrograph detail of qubits Q5 and Q9 shows the placement (red outline) of the Josephson junction relative to the transmon capacitor and ground plane. Corresponding profiles of the superconducting film thicknesses near a junction is shown in Fig. 8.
