QPIXL++ - Quantum Image Pixel Library

The QPIXL library currently supports the compilation of compressed quantum circuits for Flexible Representation of Quantum Images (FRQI) that contain quadratically fewer gates than previous implementations of FRQI and are NISQ-friendly as the circuits only contain CNOTs and single qubit rotation gates.

How to run?

The QPIXL++ package uses the CMake build system (CMake version ≥ 3.16). The recommended way of building QPIXL++ is as follows:

1. Install

    git clone https://github.com/QuantumComputingLab/qpixlpp.git
   

2. CMake

    cd qpixlpp
    mkdir release
    cd release
    cmake -DCMAKE_BUILD_TYPE=Release ..
    make -j8
   

3. Run tests

    ./test/qpixl_tests
   

4. Examples

    ./examples/compressedFRQI ../examples/Example0.pgm ../examples/output 0 0
   

   For help

    ./examples/compressedFRQI --help
   

5. Generate documentation

    doxygen doxygen.dox
