论文摘要
当前建造量子计算机的努力主要集中在两国量子位上，这通常涉及抑制易于使用的更高状态。在这项工作中，我们打破了此类抽象，并合成了广义D-state Qudits上门的短期控制脉冲。我们提出了增量脉冲重新种子，这是一种实用的方案，可通过以先前的结果为优化器迭代地播种优化器，从而将最佳控制软件引导为最低的脉冲脉冲。我们发现，通过对传输的一qudit大门进行显式脉冲优化，希尔伯特空间维度与栅极持续时间之间的近线性关系。我们的结果表明，QUDIT操作比现实感兴趣的实际制度中预期的要高得多，并且有可能显着提高当前硬件的计算能力。
Current efforts to build quantum computers focus mainly on the two-state qubit, which often involves suppressing readily-available higher states. In this work, we break this abstraction and synthesize short-duration control pulses for gates on generalized d-state qudits. We present Incremental Pulse Re-seeding, a practical scheme to guide optimal control software to the lowest-duration pulse by iteratively seeding the optimizer with previous results. We find a near-linear relationship between Hilbert space dimension and gate duration through explicit pulse optimization for one- and two-qudit gates on transmons. Our results suggest that qudit operations are much more efficient than previously expected in the practical regime of interest and have the potential to significantly increase the computational power of current hardware.
