D-Wave has successfully demonstrated 3D analog-digital quantum simulation of higher-order topological insulators using up to 728 qubits on an Advantage2 superconducting quantum annealing processor. This achievement, detailed in a research study on arXiv, involved new analog-digital quantum control protocols to measure localized boundary modes and extract 3D bulk topological invariants. This breakthrough confirms the utility of analog-digital quantum annealing hardware as a programmable simulator for condensed matter physics and topological materials.
