TORONTO and MUNICH, February 25, 2026 -- Xanadu Quantum Technologies Inc. (“Xanadu”), a leading photonic quantum computing company, today announced that it has successfully integrated PennyLane and its Catalyst compiler with the Munich Quantum Toolkit (MQT). MQT is developed by teams at the Chair for Design Automation of the Technical University of Munich (TUM) and the Munich Quantum Software Company (MQSC) 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.

“This integration represents a significant step forward for the quantum software ecosystem and a great collaboration between leading players from Canada and Europe,” said Robert Wille, Full Professor representing TUM.

Lukas Burgholzer, Chief Technology Officer of MQSC, adds: “By bringing MQT's advanced tools for verifying and optimizing quantum programs directly into the Catalyst infrastructure, we are giving researchers and developers the best of both worlds: a convenient frontend with state-of-the-art tools underneath that run automatically and efficiently.”

“To make quantum computing practical, we need a software stack that is both modular and high performing. Our work with TUM and MQSC demonstrates the power of unifying tools with unique specializations into a single, cohesive workflow,” said Christian Weedbrook, Founder and Chief Executive Officer of Xanadu. “We are accelerating the development cycle and ensuring that quantum programs are not only faster but also more efficient by enabling PennyLane users to leverage MQT’s methods without changing their code structure.”

The project highlights the use and value of modular infrastructure for quantum software. Connecting complementary technologies from different sources – such as those from Xanadu, TUM, and MQSC – allows for a “mix-and-match” approach that unlocks the software stack to become more accessible for users. The result is a flexible infrastructure where specialized technologies can interoperate freely, fostering greater connectivity across the growing quantum software ecosystem.
