The method requires measuring O(n²) stabilizers instead of exponentially many, with stabilizer weights bounded by twice the graph's maximum degree. For cluster and ring-graph states, only constant-weight stabilizers are needed. The approach uses semidefinite programming to reduce measurement requirements and demonstrates noise-robust performance on simulated microwave photonic graph states from superconducting circuits, enabling practical benchmarking of large-scale quantum devices where joint measurements are restricted. ## Full article daily.dev links to this article rather than hosting it.
