▲ 6 qubits surround a computational resonator to form a hexagonal Star module. These hexagonal modules are tiled to form the IQM Constellation architecture, achieving scalability. Each qubit has a connectivity of 12, a significant increase from the connectivity of 4 in the traditional square lattice.
