Analog counterdiabatic quantum computing

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.
