QOPS: A Compiler Framework for Quantum Circuit Simulation Acceleration with Profile Guided Optimizations

QOPS is a quantum compiler framework that enables profile-guided optimization (PGO) for faster quantum circuit simulations. It collects performance data during simulation and uses it to generate an optimized version of the circuit, improving efficiency.

Architecture

• qcor-pgo: quantum compiler frontend (qir-alliance/qcor f685743), MIT license
• xacc-pgo: quantum compiler backend (eclipse/xacc c7c4c795), dual licensed - Eclipse Public License and Eclipse Distribution License
• stateVector: storage-based statevector quantum circuit simulator (drazermega7203/stateVector a5639e6), GPL-3.0 license
• llvm-pass-qpgo: Clang/LLVM instrumenter for quantum circuit simulator, BSD-3-Clause license
• qviz-gui: interactive quantum performance analyzer and debugger, GPL-3.0 license
• qcor-code: example quantum programs, BSD-3-Clause license
• qfusion-opt: a novel gate fusion workflow and algorithm that leverages profile-informed techniques, Apache-2.0 license
  • qiskit-aer: a high performance simulator for quantum circuits written in Qiskit (b77f005; tag:0.14.2), Apache-2.0 license

Requirements

• Ubuntu 20.04 LTS
• Clone QOPS to ~/QOPS, and move stateVector to home (mv ~/QOPS/stateVector ~/stateVector)
• Follow AIDE-QC - Build the LLVM-CSP Fork to clone, build, and install LLVM at ~/.llvm/
• Follow AIDE-QC - Build Everything from Source to build XACC (xacc-pgo) and QCOR (qcor-pgo) from source
