Xanadu and GlobalFoundries Team Up to Mass-Produce Quantum Computing Hardware

Xanadu Moves Quantum Components Toward High-Volume Manufacturing

Canadian quantum computing company Xanadu has partnered with semiconductor manufacturer GlobalFoundries to develop and manufacture photonic components for utility-scale quantum computers. Announced October 6, the multi-year agreement aims to move Xanadu’s photonic technology from laboratory-scale production toward industrial manufacturing.

The initial work will focus on two key technologies: ultra-low-loss silicon nitride (SiN) photonics and superconducting nanowire single-photon detectors (SNSPDs). Manufacturing will take place through GlobalFoundries’ 300 mm production line in Malta, New York.

The partnership is designed to address one of the major challenges facing quantum computing: producing specialised hardware reliably and at a scale beyond research prototypes.

Silicon Nitride Photonics and Single-Photon Detectors

Xanadu’s approach uses photons to carry quantum information. Its SiN photonics platform is designed to guide light through quantum circuits with very low signal loss, while SNSPDs detect and measure individual photons produced during quantum computations.

The companies say combining the two technologies forms an important part of Xanadu’s photonic quantum architecture. Xanadu has selected SNSPDs as its photon-number-resolving detector platform for its utility-scale systems, with the company expecting the technology to improve system speed while reducing the amount of chip hardware required.

Moving these components onto GlobalFoundries’ 300 mm manufacturing infrastructure could also give Xanadu a more repeatable production process than laboratory fabrication. The companies described the transition as a move from lab-scale prototyping toward industrial-grade production.

Partnership Targets Fault-Tolerant Quantum Systems

The manufacturing agreement is expected to support Xanadu’s upcoming fault-tolerant quantum computing demonstrators. The companies are also exploring additional work on high-performance quantum modules that could improve the power and utility of future photonic systems.

For Xanadu, the partnership is part of its longer-term effort to develop hardware capable of supporting quantum computing at data-center scale. However, the agreement itself does not mean that utility-scale or fault-tolerant quantum computers are already commercially available.

GlobalFoundries brings experience in manufacturing photonic and semiconductor components on large production wafers. Its 300 mm facility in New York provides Xanadu with an industrial manufacturing platform for transferring its existing photonic technologies out of the research environment.

Building a Manufacturing Base for Quantum Computing

The partnership comes as quantum computing companies increasingly focus on the manufacturing challenge alongside advances in quantum algorithms and processor design. Scaling quantum hardware requires specialised components to be produced with consistent performance while keeping manufacturing complexity under control.

Xanadu says the GlobalFoundries collaboration will provide a manufacturing foundation for its future quantum systems and potential quantum data-center hardware. The companies will initially concentrate on SiN photonics and SNSPDs before exploring additional quantum modules.

The agreement therefore represents a step toward making photonic quantum hardware more manufacturable, although further engineering and development will be required before the technology reaches large-scale commercial deployment.
