Qrisp

Eclipse Qrisp (also referred to as Qrisp) is an open-source high-level quantum programming framework designed to simplify the implementation and development of quantum algorithms. Initially developed by Fraunhofer FOKUS (Quality Engineering unit, Berlin), Qrisp enables programmers to write complex quantum circuits using familiar constructs (variables, loops, etc.) while automating low-level tasks like gate assembly and qubit management. Its design shifts the emphasis from hardware-specific gate manipulation to modern software paradigms, making quantum code more accessible to classical developers. The framework is written in Python and integrates with standard scientific libraries (e.g. NumPy, NetworkX, TensorFlow).

Qrisp is released as open-source software under an Eclipse Foundation project, and was publicly funded by the German Federal Ministry for Economic Affairs and Climate Action for its initial development.
