Tower Semiconductor, a leading global foundry for high, value analog semiconductor manufacturing, and Xanadu, a pioneering company in photonic quantum computing, have announced that they are expanding their strategic collaboration to accelerate the development and manufacturability of advanced silicon photonics for fault, tolerant quantum computers.
Building on a series of successful joint tapeouts and technical achievements, the two companies have co-engineered a tailored production flow to support Xanadu’s custom material stack on Tower’s high-volume silicon photonics platform. This enhanced platform is designed to address both scalability and performance demands as quantum computing systems grow in complexity, meeting the rigorous requirements of large-scale quantum information processing.
“Our work with Tower has been instrumental in moving our hardware from concept to prototype to demonstrator systems within a scalable manufacturing environment,” said Christian Weedbrook, Founder and CEO of Xanadu.

“By combining our architectural breakthroughs, fabrication process engineering and design innovations with Tower’s world-class technology and manufacturing expertise, we are building the foundation for a truly useful quantum computer.”
Dr. Ed Preisler, Vice President and General Manager of Tower’s RF Business Unit, emphasized the broader applicability of the partnership: “Xanadu is advancing one of the most scalable quantum architectures in the industry, and we’re pleased to deepen our collaboration to support manufacturable scale,” he said.
“This reinforces the broad applicability of our platform across multiple advanced domains including quantum computing, data centers, telecom and automotive applications.”
Ongoing projects in the partnership are focused on maximizing the performance of key photonic components through standard product processing methods, like ultra, low, loss silicon nitride (SiN) and integrated photodiodes. Such advancements allow Xanadu to test its latest circuit layouts on a well, established high, volume production platform, thus paving the way for commercial, scale photonic quantum computing.
