Xanadu’s PennyLane integrates with Munich Quantum Toolkit

Xanadu Quantum Technologies integrated PennyLane and its Catalyst compiler with the Munich Quantum Toolkit. MQT is developed by teams at the Chair for Design Automation of the Technical University of Munich and the Munich Quantum Software Company and enables an interoperable and scalable quantum software stack, based on mature classical compilation technology. This collaboration creates more accessible quantum software by connecting a user-friendly Python interface through Xanadu’s PennyLane to high-performance code that is the foundation of Catalyst and MQT. As quantum hardware scales, quantum programs are becoming exponentially more complex, and compiling these larger programs efficiently is expected to become a major challenge in the quantum computing stack. Together, PennyLane, Catalyst, and MQT’s Core project bring complementary capabilities. PennyLane offers an intuitive interface for writing hybrid quantum-classical programs, while Catalyst and MQT handle the heavy-lifting for compilation by using specialized, high-performance tools that have been built over decades in classical computing. Users can now access advanced compilation techniques from both tools by adding a single line of code to their PennyLane programs. This integration works seamlessly in the background and lowers barriers for designing quantum algorithms using software – allowing researchers and developers to focus on innovation rather than managing complex software configurations.
