摘要

Harnessing the analog capacity of quantum processors at the algorithmic level is key to solving computationally hard problems. Neutral atoms offer analog capabilities supporting hundreds of qubits, but state-of-the-art adiabatic protocol struggles with nonadiabatic errors, restricting scalability due to finite coherence times. To address this, we propose and experimentally demonstrate a tailored analog counterdiabatic quantum computing (ACQC) protocol to enhance the computational capabilities of neutral atoms by mitigating non-adiabatic transitions and facilitating rapid and high-quality solutions. We apply it to solve the maximum independent set problem with up to 100 qubits, achieving over 3-fold speedup in convergence time and solution quality within a short evolution time of the processor, as compared to adiabatic method. Our method shows scalibility of the application of neutral atom processors establishing ACQC as a promising pathway toward quantum advantage for real-world industrial applications.
