论文摘要
量子信息平台的可扩展相干控制硬件正优先增长，因为它们的可用量子数继续增加。随着这些系统规模的规模，需要更多的校准步骤，从而导致系统不稳定性作为校准参数漂移而挑战。此外，运行较大深度的电路所需的庞大数据往往会气球，尤其是在实施需要先进调制技术的最新动态止回门时。我们提出了一个控制系统，该系统通过相结合的新功能来解决陷阱离子系统的这些挑战，这些功能消除了对手动簿记的需求，通过门压缩方案减少数据传输带宽要求以及其他自动化错误处理技术。此外，我们描述了一种应用分阶段优化的嵌入式脉冲编译器，包括解析输出产品的压缩中间表示，执行压缩门数据的原位突变，以支持高级算法反馈以考虑到漂移，并且可以完全在芯片上运行。
Scalable coherent control hardware for quantum information platforms is rapidly growing in priority as their number of available qubits continues to increase. As these systems scale, more calibration steps are needed, leading to challenges with system instability as calibrated parameters drift. Moreover, the sheer amount of data required to run circuits with large depth tends to balloon, especially when implementing state-of-the-art dynamical-decoupling gates which require advanced modulation techniques. We present a control system that addresses these challenges for trapped-ion systems, through a combination of novel features that eliminate the need for manual bookkeeping, reduction in data transfer bandwidth requirements via gate compression schemes, and other automated error handling techniques. Moreover, we describe an embedded pulse compiler that applies staged optimization, including compressed intermediate representations of parsed output products, performs in-situ mutation of compressed gate data to support high-level algorithmic feedback to account for drift, and can be run entirely on chip.
