Spectral Detection of Correlated Errors on Superconducting Quantum Hardware via Parity-Circuit Canaries

Standard device characterization protocols, such as Randomized Benchmarking (RB), typically report averaged, independent error rates per qubit. However, these methods are largely blind to correlated errors between neighbouring qubits: errors that fundamentally break the independe...
