Fast Free Fermion Compiler: F3C++

F3C++ is an object-oriented, fully templated C++ package for compiling time-evolution quantum circuits of spin Hamiltonians that can be mapped to free fermions. F3C++ is build on top of QCLAB++ and provides I/O through openQASM making it compatible with quantum hardware.

How to run?

The F3C++ package uses the CMake build system (CMake version ≥ 3.16). The recommended way of building F3C++ is as follows:

1. Install

    git clone https://github.com/QuantumComputingLab/f3cpp.git
   

2. CMake

    cd f3cpp
    mkdir release
    cd release
    cmake -DCMAKE_BUILD_TYPE=Release ..
    make -j8
   

3. Run tests

    ./test/f3c_tests
   

4. Examples

    ./examples/f3c_time_evolution_XY ../examples/XY.ini
    ./examples/f3c_time_evolution_TFXY ../examples/TFXY.ini or
   
    python3 python/f3c_time_evolution_XY.py ../examples/XY.ini
    python3 python/f3c_time_evolution_TFXY.py ../examples/TFXY.ini
   

5. Generate documentation

    doxygen doxygen.dox
