A CNN trained on synthetic data can infer the dephasing noise spectrum of IBM transmon qubits from a single CPMG decay curve, enabling rapid and time-resolved noise characterization.
After determining the opti- mal amplitude for the square-shaped π-pulse, we performed sequential T1 and T2 decay experiments using a CPMG-32 pulse protocol
