Quantum computing hardware is much more susceptible to errors than classical hardware. While quantum error correction can combat these errors, the noise affecting the quantum hardware must be understood to apply the proper error-correcting code. Presenting an approach for determining in real time whether qubit errors are correlated, the authors simultaneously monitor two fluxonium qubits and measure the correlations between their relaxation times. This analysis method and architecture can be generalized to multiqubit systems, where applying the right error correction is crucial for reliable computation.
