This repository provides source code for Robustness of Magic(RoM) calculation, stabilizer fidelity (for mixed state) calculation, and generating all the pure stabilizer states in Pauli-basis.
This is also the supplemental material for our paper, "Handbook for Quantifying Robustness of Magic"(2024) (quantum).
The data about A matrix, which is used in naive LP (conventional method) for calculating the RoM. Please see data/README.md for details.
The images, tables, and source codes for the paper. All the images in the paper are generated by the source codes in this directory.
The Python library for RoM calculations.
We require two setups to run the code.
It is recommended that you prepare a new virtual python environment and run pip install -r requirement.txt to ensure that libraries are compatible.
The only file written in C++ is exputils/dot/fast_dot_products.cpp, which is the most important part of our source code with fully commented.
You need to compile the source code with the following options in the directory where the source code is located.
g++ exputils/dot/fast_dot_products.cpp -o exputils/dot/fast_dot_products.exe -std=c++17 -lz -O2 -DNDEBUG -mtune=native -march=native -fopenmpThe meaning of each option is as follows:
| option | meaning |
|---|---|
| -o | output file name |
| -std=c++17 | use C++17 |
| -lz | use zlib (to use npz files in C++) |
| -O2 | optimization level 2 (-O3 might be worse than -O2) |
| -DNDEBUG | disable assertions (if you want to debug, remove this option) |
| -mtune=native | optimize for the machine you are using |
| -march=native | optimize for the machine you are using |
| -fopenmp | use OpenMP (for parallelization) |
The tutorial notebook is available at tutorial.ipynb.
