Transition edge Sensor
Joining Forces with Applied Materials to Standardise the Production of Quantum Components
Xanadu, a well-known brand in photonic quantum computing, has announced a major partnership with materials engineering company Applied Materials, Inc. The two businesses are collaborating to create the first high-volume 300 mm technique that can be used to create superconducting transition edge sensors (TESs). In order to scale up quantum computing hardware using well-established semiconductor manufacturing techniques, this alliance is an essential first step.
Photon-number-resolving detectors (PNRs) are known to rely heavily on superconducting transition edge sensors (TESs). Xanadu’s photonic quantum computers rely on these detectors as essential components to help with the qubit state preparation procedure. Therefore, the future scalability and performance of transition edge sensors TESs’ machines depend on the development of a dependable, high-volume production method.
Xanadu’s partnership comes as the company looks to the future of quantum computing, particularly the creation of utility-scale photonic quantum computers and, eventually, whole quantum data centres. The business recently showed off its modular, scalable, and networkable Aurora quantum computer, which was featured in a Nature article. This accomplishment opened the door for utility-scale goals, but achieving these goals will necessitate a significant change in the way parts are made. For several components, including transition edge sensors TESs for PNRs, mass semiconductor manufacturing capabilities are required in order to reduce production costs and meet the stringent standards for detector performance, quality, and production volume required for large-scale systems.
For TES fabrication, the use of a 300 mm platform is especially important. Since this scale is typical in the semiconductor sector, Xanadu may take advantage of the most cutting-edge fabrication tools on the market by creating a procedure that works with them. The Head of Fabrication Process Engineering at Xanadu, Elliott Ortmann, stated that this capability is anticipated to produce devices that are of superior quality and performance.According to Ortmann, “It have to continuously push what is possible in the fab because utility-scale quantum computers have exacting fabrication processing demands.” As a “tremendous collaborator” over the years, Applied Materials was also commended by him.
Applied Materials contributes decades of experience with 300 mm semiconductor platforms, as well as knowledge of sophisticated materials engineering and process management, which are crucial for meeting Xanadu’s TES design specifications. Their partnership is focused on “developing scalable fabrication approaches that can create better quantum devices for the industry,” said Dr. Robert Visser, Vice President of Engineering in the Office of the CTO at Applied Materials. He emphasised that Applied’s decades of experience in advanced materials engineering and process control are necessary for Xanadu’s TES design.
This is not the first time the two companies have worked together. On materials optimisation for TES fabrication techniques, they have previously worked together. The current project expands on this framework by concentrating on modifying the fabrication procedure to fit the 300 mm platform, which is the industry standard.
The partnership has a well-defined timetable. The teams want to show off the first 300 mm platform designed especially for constructing transition edge sensors TESs for PNRs within the next year. The platform is expected to provide a preliminary demonstration of its capabilities by the end of 2025. After this first success, the Xanadu and Applied Materials teams intend to ramp up for mass production after further fine-tuning the platform’s performance to satisfy the demanding requirements of high-throughput and high-reliability fabrication needed for quantum computing components.
Xanadu was established in 2016 with the goal of creating practical, widely available quantum computers. Beyond creating hardware, the company is renowned for spearheading the creation of PennyLane, an open-source software library for creating applications and quantum computing. Xanadu is currently attempting to reduce optical loss in their systems to provide fault tolerance, which is another crucial step towards reliable, utility-scale quantum computing, while concentrating on manufacturing scalability.

Xanadu and Applied Materials’ collaboration to industrialize the production of essential quantum components like transition edge sensors TESs reflects the quantum industry’s shift from laboratory-scale prototypes to manufacturing processes that can produce large quantities of high-quality components for large-scale quantum systems. Standardization and scaling are needed to reduce costs and accelerate the implementation of powerful quantum computers, especially using semiconductor infrastructure like the 300 mm platform.
