Three-panel paper figure made of drawings and data plots, from an arXiv paper by J. A. Montanez-Barrera, Kristel Michielsen and David E. Bernal Neira (2025-05-28) on benchmarking processors with linear-ramp QAOA. Panel (a) draws the qubit coupling graphs of 5-, 20-, 127-, 133- and 156-qubit processors, including IBM Heron devices; panels (b) and (c) plot approximation ratio against the number of QAOA layers. Notice the fixed nearest-neighbour lattices: the sparse heavy-hex patterns versus the denser square lattice limit which qubits can interact directly.“Fig. 3 — NL-based benchmarking using LR-QAOA for WMC problems; (a) QPU layouts used in each…” by J.
