Xanadu, EVG advance photonic quantum packaging
Partnership focuses on heterogeneous integration and wafer bonding to move photonic quantum hardware from lab prototypes to high-volume manufacturing.
Xanadu Quantum Technologies has announced a strategic partnership with EV Group to develop advanced integration processes aimed at scaling photonic quantum computing hardware.
The collaboration will focus on Heterogeneous Integration and wafer-bonding technologies, enabling the integration of multiple material platforms, including silicon, lithium niobate, and III–V semiconductors onto unified photonic chips.
These approaches are widely seen as essential for next-generation high-performance and quantum systems.
By leveraging EVG’s industrial wafer-bonding tools, the partners aim to transition the fabrication of Xanadu’s photonic quantum chips from research environments to scalable semiconductor manufacturing.
The effort is intended to address one of the key challenges in quantum computing: producing complex, high-performance hardware at volume.
“Heterogeneous integration is the key to unlocking the next generation of photonic performance,” said Christian Weedbrook, founder and CEO of Xanadu. “Working with EV Group allows us to push the boundaries of what’s possible on-chip, bringing us closer to a useful, large-scale quantum data centre.”
EVG emphasised the role of advanced packaging techniques in enabling emerging computing paradigms.
“This partnership demonstrates how established semiconductor technologies can accelerate next-generation high-performance computing, with quantum as the next frontier,” said Paul Lindner, executive technology director at EVG.
The collaboration reflects a broader industry shift toward integrating diverse materials and functions at the wafer level to overcome scaling limits in both photonics and electronics.
For photonic quantum computing in particular, precise bonding and ultra-clean interfaces are critical to maintaining optical performance across complex chip architectures.
By aligning with established semiconductor manufacturing processes, the companies aim to accelerate the path toward commercially viable, large-scale quantum systems—moving beyond laboratory demonstrations to industrial-scale production.
