Strengthening the manufacturing foundation for commercial-scale photonic quantum computing

MIGDAL HAEMEK, Israel, and Toronto, ON, February 19, 2026 - Tower Semiconductor , the leading foundry of high-value analog semiconductor solutions, and Xanadu, a leading photonic quantum computing company, today announced an expansion of their collaboration in developing advanced silicon photonics for fault tolerant quantum computers based on Tower’s high-volume silicon photonics platform. These developments build on prior collaborative technical achievements, including a series of successful joint tapeouts to test and refine Xanadu’s designs on Tower Semiconductor process flows.

Xanadu and Tower have co-engineered a unique production flow for Xanadu’s custom material stack, delivering a manufacturing-aligned, architecture-compatible platform for next-generation photonic quantum hardware. This custom stack is designed to sustain both scalability and performance as systems grow in complexity, meeting the 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."

“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,” said Dr. Ed Preisler, Vice President and General Manager of RF Business Unit, Tower Semiconductor . “This reinforces the broad applicability of our platform across multiple advanced domains including quantum computing, data centers, telecom and automotive applications.

Current developments focus on optimizing the performance of critical components using standard product flows for ultra-low loss silicon nitride (SiN) and integrated photodiodes. These projects allow Xanadu to validate its cutting-edge photonic circuit designs on an established high-volume manufacturing platform. In addition, as the quantum computing industry advances toward commercial scale systems, this collaboration is set to meet the manufacturability requirements of large-scale photonic quantum computing.
