SUMMARY:Large-Scale Parallel Tensor Network Quantum Simulator
DESCRIPTION:Workshop\n\nLarge-Scale Parallel Tensor Network Quantum Simula
tor\n\nLykov, Schutski, Vinokour, Alexeev\n\nIn this work, we present a ne
w large-scale parallel quantum circuit simulator. It is based on the tens
or network contraction technique to represent quantum circuits. We propos
e a novel late parallelization algorithm to split tensor expressions. By
using our MPI/OpenMP parallelization scheme, we have significantly increas
ed the size of circuits we can compute, as well as the speed of calculatio
ns.\n\nThe simulator benchmarking studies were performed for Quantum Appro
ximate Optimization Algorithm (QAOA) circuits. We computed 210 qubit QAOA
circuits with depth 1,785 gates on 1,024 nodes and 213 TB of memory on th
e Theta supercomputer, which is based on Intel Xeon Phi architecture. To t
he best of our knowledge, this constitutes the largest QAOA quantum circui
t simulations reported to this date.\n\nTag: Quantum Computing\n\nRegistra
