SUMMARY:Scalable Programming Workflows for Validation of Quantum Computers
DESCRIPTION:Workshop\n\nScalable Programming Workflows for Validation of Q
 uantum Computers\n\nPooser, Nguyen, Humble\n\nHybrid quantum-classical wor
 kflows have become standard methods for executing variational algorithms a
 nd other quantum simulation techniques, which are key applications for noi
 sy intermediate scale quantum (NISQ) computers. Validating these simulatio
 ns is an important task which helps gauge the progress of quantum computer
  development, and classical simulation can serve as a tool to this end. Bo
 th exact and more scalable approximate methods with quantifiable error bou
 nds can be used in validation tasks where the applicable metrics include t
 he distance from a calculable ground truth, the quality of an error model 
 fit to data, etc. Here we present a library extension that includes method
 s for validation of quantum simulations based on scalable hybrid workflows
  executable on high performance computers. We provide examples that use ap
 proximate methods based on tensor networks and stabilizer simulators to bo
 und the error of quantum simulations on NISQ hardware. The extension lever
 ages the hybrid workflows implemented in the QuaSiMo library. Notably, the
  validation methods can be used as backends in the XACC programming framew
 ork, so that hardware execution and model simulation can be interchanged a
 nd compared automatically, using the same algorithm code (written in C++ w
 ith QCOR extensions or Python). We provide a description and demonstration
  of selected workflow methods with cross-validation results for quantum ap
 proximate optimization (QAOA) problems and adiabatic state preparation (AS
 P) in the transverse Ising model.\n\nTag: Online Only, Algorithms, Quantum
