论文摘要
我们引入了一种新颖的量子控制方法，用于超导式矩形量子位，该方法基本上优于相干误差的精确性和鲁棒性。我们的方法利用复合脉冲（CP）有效地减轻系统特定的错误，例如量子频率和非谐度变化。通过利用CP，我们证明了量子状态之间的完整和部分种群转移，以及实施了两个必不可少的单品量子门。模拟显示常见错误率和栅极持续时间大大降低。我们方法的有效性通过四种独立的验证技术验证，强调了其用超导Qubits推进量子计算的潜力。
We introduce a novel quantum control method for superconducting transmon qubits that substantially outperforms conventional techniques in precision and robustness against coherent errors. Our approach leverages composite pulses (CP) to effectively mitigate system-specific errors, such as qubit frequency and anharmonicity variations. By utilizing CP, we demonstrate both complete and partial population transfers between qubit states, as well as the implementation of two essential single-qubit quantum gates. Simulations reveal substantial reductions in common error rates and gate durations. The effectiveness of our method is validated through four independent verification techniques, underscoring its potential for advancing quantum computing with superconducting qubits.
