论文摘要
在这项工作中，我们提出了一个新的大型量子电路模拟器。它基于张量网络收缩技术来表示量子电路。我们提出了一种基于\ steplice的新型并行化算法。在本文中，我们按照量子计算机的大小来提出要求，该量子计算机将需要用量子近似优化算法（QAOA）来证明量子计算的优势。我们在1,024个cray XC 40超级计算机theta上计算了210个QAOA电路，其中1,785个门。据我们所知，这构成了该日期报告的最大的QAOA量子电路模拟。
In this work, we present a new large-scale quantum circuit simulator. It is based on the tensor network contraction technique to represent quantum circuits. We propose a novel parallelization algorithm based on \stepslice . In this paper, we push the requirement on the size of a quantum computer that will be needed to demonstrate the advantage of quantum computation with Quantum Approximate Optimization Algorithm (QAOA). We computed 210 qubit QAOA circuits with 1,785 gates on 1,024 nodes of the the Cray XC 40 supercomputer Theta. To the best of our knowledge, this constitutes the largest QAOA quantum circuit simulations reported to this date.
