论文摘要
我们展示了中性原子设备体系结构中多量门门的脉冲级实现如何同时执行对重叠的Qubits的单量和多数门的执行，我们在一种机制中以一种机制来命名吸收。通过吸收作为基础，我们提出了一种算法，以将量子电路作为单个通道的中性原子设备上的脉冲序列安排为脉冲序列，用于单个通道，用于单量和多数栅极执行。对于任何实用相关性的量子电路，我们观察到算法会导致对可用资源的最佳利用，而这些资源无法超过不同的调度策略。我们针对试图在栅极级别最大化并行化的自定义调度程序的基准测试表明，脉冲级调度程序获得的时间与深度成正比，并且对于量子较少的量子电路最为明显。
We show how a pulse-level implementation of the multi-qubit gates in neutral-atom device architectures allows for the simultaneous execution of single- and multi-qubit gates acting on overlapping sets of qubits, in a mechanism we name absorption. With absorption as a foundation, we present an algorithm to schedule the execution of a quantum circuit as a pulse sequence on a neutral-atom device with a single channel for single- and multi-qubit gate execution. For any quantum circuit of practical relevance, we observe that the algorithm results in an optimal utilization of the available resources that cannot be surpassed by a different scheduling strategy. Our benchmarks against a custom scheduler attempting to maximize parallelization at the gate level show the time gained by the pulse-level scheduler is proportional to the depth and is most pronounced for quantum circuits with fewer qubits.
