SUMMARY:Enabling Scalable VQE Simulation on Leading HPC Systems
DESCRIPTION:Meng Wang (University of British Columbia, Pacific Northwest N
 ational Laboratory (PNNL)); Fei Hua (Rutgers University, Pacific Northwest
  National Laboratory (PNNL)); Chenxu Liu, Nicholas Bauman, and Karol Kowal
 ski (Pacific Northwest National Laboratory (PNNL)); Daniel Claudino and Tr
 avis Humble (Oak Ridge National Laboratory (ORNL)); Prashant Nair (Univers
 ity of British Columbia); and Ang Li (Pacific Northwest National Laborator
 y (PNNL))\n\nLarge-scale simulations of quantum circuits pose significant 
 challenges, especially in the context of quantum chemistry, due to the num
 ber of qubits, circuit depth, and the number of circuits needed per proble
 m. High-performance computing (HPC) systems offer massive computational ca
 pabilities that could help overcome these obstacles. We developed a high-p
 erformance quantum circuit simulator, called NWQ-Sim, and demonstrate its 
 capability to simulate large quantum chemistry problems on NERSC's Perlmut
 ter supercomputer. Integrating NWQ-Sim with XACC, we have executed QPE and
  VQE algorithms for downfolded quantum chemistry systems at unprecedented 
 scales. Our work demonstrates the potential of leveraging HPC resources to
  advance quantum chemistry and other applications of near-term quantum dev
 ices.\n\nTag: Quantum Computing, Software Engineering\n\nRegistration Cate
