论文摘要
在过去的几十年中,我们目睹了量子计算的快速增长。在当前嘈杂的中间尺度量子(NISQ)时代,量子机的能力受到骨化时间,栅极保真度和量子数量的限制。当前的量子计算应用程序远非由于脆弱的物理Qubit,远非实际的“量子至高无上”,这只能在几微秒内纠缠。最近的工作使用量子最佳控制来减少量子电路的潜伏期,从而有效地增加了量子体积。但是,该技术的主要挑战是由于较长的汇编时间而导致的大开销。在本文中,我们提出了ACCQOC,ACCQOC是一种综合的静态/动态混合工作流程,将栅极组(相当于矩阵)转换为使用QOC(量子最佳控制)的脉冲,并具有合理的编译时间预算。 ACCQOC由静态预兼容和加速动态汇编组成。通过ACCQOC的方法,我们达到了汇编时间和整体延迟的平衡点。结果表明,与每组的标准汇编相比,基于MST的加速汇编达到了9.88倍的汇编速度,同时与基于门基的汇编相比,平均降低了2.43倍的延迟延迟。
In the last decades, we have witnessed the rapid growth of Quantum Computing. In the current Noisy Intermediate-Scale Quantum (NISQ) era, the capability of a quantum machine is limited by the decoherence time, gate fidelity and the number of Qubits. Current quantum computing applications are far from the real "quantum supremacy" due to the fragile physical Qubits, which can only be entangled for a few microseconds. Recent works use quantum optimal control to reduce the latency of quantum circuits, thereby effectively increasing quantum volume. However, the key challenge of this technique is the large overhead due to long compilation time. In this paper, we propose AccQOC, a comprehensive static/dynamic hybrid workflow to transform gate groups (equivalent to matrices) to pulses using QOC (Quantum Optimal Control) with a reasonable compilation time budget. AccQOC is composed of static pre-compilation and accelerated dynamic compilation. With the methodology of AccQOC, we reached a balanced point of compilation time and overall latency. The results show that accelerated compilation based on MST achieves 9.88x compilation speedup compared to the standard compilation of each group while maintaining an average 2.43x latency reduction compared with gate-based compilation.
