论文摘要
随着嘈杂的中间量子量子（NISQ）处理器的大小和复杂性的增加，它们作为通用量子模拟器的使用将依赖于基于Trotter-Suzuki扩展的算法。我们在一个高度准确的量子处理器上运行量子模拟，并通过平衡算法（trotter）错误与当前量子硬件特定的本机错误来表明如何通过平衡算法（trotter）错误来优化模拟精度。我们进一步研究天然误差，猪肉误差和混乱的出现之间的相互作用，如时间的测量值所示
As noisy intermediate-scale quantum (NISQ) processors increase in size and complexity, their use as general purpose quantum simulators will rely on algorithms based on the Trotter-Suzuki expansion. We run quantum simulations on a small, highly accurate quantum processor, and show how one can optimize simulation accuracy by balancing algorithmic (Trotter) errors against native errors specific to the quantum hardware at hand. We further study the interplay between native errors, Trotter errors, and the emergence of chaos as seen in measurements of a time averaged fidelity-out-of-time-ordered-correlator
