    ProjectQ is an open-source software framework for quantum computing started
    at ETH Zurich. It allows users to implement their quantum programs in
    Python using a powerful and intuitive syntax. ProjectQ can then translate
    these programs to any type of back-end, be it a simulator run on a
    classical computer of an actual quantum chip.
