How to run?

⚪ install

• better prepare a working Linux system, since PySCF CANNOT run on Windows!! :(
  • it's also ok to run on Windows, but must use a pre-calculated ham file like OHhamiltonian.txt
  • and few features are unavailable, no big matter
• create venv (optional)
  • install Miniconda latest
  • conda create -n qs
  • conda activate qs
• install dependencies pip install -r requirements.txt
  • if you have CUDA on Linux, one more cmdline: pip install qiskit-aer-gpu
• test qiskit installation
  • python _tutorial_qiskit_vqe.py
• clone the code & data base git clone https://github.com/qccontest/QC-Contest-Demo
• test demo code runnable
  • python _test_examplecode.py -T 2; this might be very slow, just be patient :(
  • python _test_NoiseModel_and_SystemModel.py

⚪ run the results for submission

• run jupyter notebook run_submission.ipynb

⚪ run development

⚠ for Windows where PySCF is not available, you could only run with a pre-calculated ham file

• python run.py, the ham will be computed by Qiskit-PySCF (Linux only!)
• python run.py -H ham_file to specify an arbitary pre-calculated ham file
  • run the contest ham: python run.py -H txt or python run.py -H QC-Contest-Demo\Hamiltonian\OHhamiltonian.txt
  • run the ChemiQ pre-computed ham: python run.py -H playground\run_chq.ham
    • this ham seems to be inconsist with the Qiskit-PySCF analyzed one, with energy-diff approximately right the value of nuclear_repulsion_energy
    • have no idea about know whether it is a bug or feature :(
