Xanadu Quantum Technologies secured a multi-year manufacturing agreement with GlobalFoundries for quantum photonic hardware production.
The chip manufacturer will fabricate Xanadu’s photon detection systems and silicon nitride photonics at its Malta, New York 300mm plant.
XNDU shares climbed 9% following the announcement, while GlobalFoundries stock increased approximately 1%.
The partnership follows GlobalFoundries’ recent $375 million Commerce Department agreement that granted the federal government about 1% equity.
This collaboration represents Xanadu’s transition from research-phase development to commercial-scale manufacturing.

Shares of Xanadu Quantum Technologies climbed 9% Tuesday following the announcement of a manufacturing collaboration with GlobalFoundries. Trading volume pushed the stock to an intraday peak of $4.82.

The partnership connects Xanadu with GlobalFoundries, an established semiconductor fabrication company. GlobalFoundries will handle volume production of two essential elements of Xanadu’s photonic quantum computing architecture.

These elements include ultra-low loss silicon nitride photonic circuits and superconducting nanowire single-photon detectors. The detection technology measures individual photons within light pulses—a foundational requirement for quantum systems that leverage light particles for computational operations.

Manufacturing Agreement Details

Fabrication operations will utilize GlobalFoundries’ 300-millimeter production line located in Malta, New York. According to both organizations, this agreement represents a significant transition from laboratory prototypes to full industrial manufacturing capacity.

Christian Weedbrook, CEO of Xanadu, described high-volume production capabilities as “fundamental to delivering quantum computing at scale.” The partnership enables Xanadu to enhance and broaden its photonic quantum platform, he noted.

Nicholas Sergeant, who oversees GlobalFoundries’ Quantum Technology Solutions division, shared similar observations. The collaboration establishes a manufacturing pathway for components required in future fault-tolerant quantum architectures, he explained.

Products from this manufacturing arrangement will support Xanadu’s upcoming fault-tolerant quantum demonstration systems. Both partners indicated they’re exploring additional quantum hardware modules for potential future development.

GlobalFoundries Expands Quantum Initiatives

GlobalFoundries has established multiple quantum computing relationships. The semiconductor manufacturer completed a $375 million Commerce Department agreement last month that launched its Quantum Technology Solutions business unit.

The federal funding included an equity component: the U.S. government acquired approximately 1% ownership in GlobalFoundries through the transaction. This initiative reflects broader federal efforts to establish domestic quantum hardware production capabilities.

GlobalFoundries holds “Trusted Foundry” designation from the Department of Defense. This certification validates the company’s compliance with stringent federal security requirements, positioning it favorably for government quantum projects.

The foundry’s quantum involvement extends back years. GlobalFoundries acquired IBM’s chip manufacturing operations in 2015, strengthening its advanced semiconductor production capabilities.

Xanadu began public trading in March following a special-purpose acquisition company transaction. The firm positions itself as the initial publicly traded company focused exclusively on photonic quantum computing technology.

The listing occurred during a surge of quantum company public offerings, with Infleqtion and Horizon Quantum also debuting within weeks. Xanadu has received substantial government support from Canadian agencies.

The company has yet to secure comparable U.S. federal contracts and was excluded from a May funding announcement. Nevertheless, Xanadu maintains connections to American defense research programs: the firm has advanced through DARPA’s quantum benchmarking initiative, which evaluates and validates quantum computing technologies from participant organizations.
