Xanadu and Applied Materials Collaborate on Quantum Computing

In a significant move for the future of quantum computing, Xanadu Quantum Technologies, based in Toronto, has announced a collaboration with Applied Materials, Inc. This partnership focuses on pioneering a 300 mm high-volume-compatible process for the production of superconducting transition edge sensors (TESs).

These sensors form a crucial part of photon-number-resolving detectors (PNRs), vital for qubit state preparation in Xanadu's innovative photonic quantum computers. The collaboration aims to address the increasing demand for mass semiconductor manufacturing capabilities, particularly to enhance performance and efficiency while reducing production costs.

A Leap Toward Scalability and Utility

Earlier in 2025, Xanadu achieved a notable breakthrough with its Aurora quantum computer, showcasing a modular, scalable quantum computing system that can function within a network. This development represents a leap towards the vision of utility-scale photonic quantum computers. However, to fully realize this potential, minimizing optical loss across various components is essential, particularly as they set their sights on establishing a comprehensive quantum data center.

Elliott Ortmann, the Head of Fabrication Process Engineering at Xanadu, stated, "Utility-scale quantum computers have exacting fabrication processing demands that require us to continually push what is possible in the fab. Collaboration with Applied Materials has been invaluable, and we eagerly anticipate overcoming new challenges together. Developing the first 300 mm process for TESs will enable us to utilize cutting-edge fabrication technologies, leading to superior quality and performance."

This collaboration hinges on building upon existing work focused on optimizing TES fabrication techniques, with both teams planning to demonstrate the inaugural 300 mm platform for TESs by late 2025. Once foundational demonstrations are complete, they intend to further refine these technologies to meet the rigorous requirements for high throughput and reliability before ramping up to mass production.

A Vision for Quantum Innovation

Applied Materials' participation is instrumental due to its expertise in the semiconductor field, providing advanced solutions that will be essential in transforming the quantum device landscape. Dr. Robert Visser, Vice President of Engineering at Applied Materials, remarked, "Our focus is on developing scalable fabrication methods that can enhance the performance of quantum devices. The advanced materials engineering and process control needed for Xanadu's TES design is key to achieving success in this area."

Looking Ahead

As this partnership progresses, Xanadu aims to stay at the forefront of quantum computing innovation. Founded in 2016, their mission extends beyond technological development to making quantum computing accessible globally. Their open-source software library, PennyLane, exemplifies this commitment by providing resources for developers and researchers alike.

The collaboration between Xanadu and Applied Materials exemplifies a strategic alliance, likely to set new standards in the emerging field of quantum technology. As they work toward optimizing fabrication processes, the realization of scalable, utility-grade quantum systems becomes increasingly tangible. This endeavor is not just about technological evolution; it represents a significant step toward harnessing the full potential of quantum computing for the greater good—bringing the future of computing into the hands of everyone.

For those interested in following this journey, further updates are anticipated as both companies outline their milestone achievements in the upcoming months.
