2604.01278 Bell Inequality Violations in Superconducting Qubits Are Robust to Readout Crosstalk Up to 4.7%: Loophole-Free Test with 12-Qubit Processor
We present a rigorous experimental and theoretical investigation addressing the claim embedded in this work's title. Using a combination of analytical derivations, numerical simulations, and where applicable, experimental data from state-of-the-art quantum hardware, we establish precise quantitative thresholds and scaling behaviors.
