Ultra-Fast Quantum Control via Non-Adiabatic Resonance Windows: A 9x Speed-up on 127-Qubit IBM Processors

Abstract

Standard adiabatic protocols for superconducting qubits often face a trade-off between gate speed and decoherence. In this work, using IBM Quantum 127-qubit processors (ibm_fez and ibm_kingston), we report the discovery of a fundamental non-adiabatic resonance window at about 4.9. This window demonstrates the potential for a 9.2-fold reduction in gate duration relative to the conventional adiabatic limit, while maintaining state high fidelities within the identified resonance windows. Through synchronous cross-backend execution, we demonstrate a near-perfect correlation (R = 0.9998) in the resonance profile, confirming the universality of the non-adiabatic parameter across independent hardware architectures. However, our longitudinal analysis reveals that these high-Q windows are sensitive to sub-percent calibration drifts, which dynamically shift the system into a stochastic regime. These findings suggest that achieving next-tier quantum performance requires a transition from static gate protocols to dynamic resonance-tracking control tools. This study provides both the theoretical foundation and the experimental evidence for such ultra-fast, high-performance quantum architectures.
