IonQ, a global leader in quantum computing platforms, has officially completed its acquisition of SkyWater Technology, the largest exclusively U.S.-owned and operated semiconductor foundry.
The strategic transaction establishes an integrated domestic framework for quantum hardware manufacturing. By pairing IonQ’s quantum architecture with SkyWater’s pure-play semiconductor fabrication facilities, the combined entity aims to scale next-generation quantum chip development, secure sovereign supply chains, and deliver commercial-grade quantum applications for defense, aerospace, and enterprise markets.
Unifying Quantum Innovation with Domestic Semiconductor Fabrication
The acquisition secures a reliable, high-volume manufacturing pipeline for IonQ’s trapped-ion and semiconductor-based quantum system roadmaps. In addition to powering IonQ’s internal product evolution, the combined infrastructure will continue operating as a commercial merchant supplier, delivering advanced packaging, wafer fabrication, and specialized quantum componentry to the broader technology ecosystem.
SkyWater will function as a direct subsidiary of IonQ, maintaining its commercial operations under the SkyWater brand to ensure uninterrupted service to its existing public and private sector foundry client base.

“Acquiring SkyWater crystalizes IonQ’s vision to serve as a technology leader, merchant supplier and ecosystem enabler across the entire quantum industry. We are investing in capabilities from quantum foundry and advanced packaging to manufacturing and commercialization that the quantum ecosystem requires for future growth,” said Niccolo de Masi, Chairman and Chief Executive Officer of IonQ. “Building upon our existing merchant supplier track record providing quantum solutions for our customers, we expect this acquisition to accelerate all quantum platforms across the industry.”
“This combination enables IonQ to drive our quantum computing roadmap and secure a fully scalable supply chain domestically. It unlocks IonQ‘s semiconductor-based approach to manufacturing new generations of our quantum computers, while ensuring SkyWater’s ability to deliver the excellent quality and attention customers expect,” said de Masi, who added, “Secure chip design, fabrication, and packaging will deliver vertical integration across our full stack of quantum applications for land, sea, air, and space.”
“Joining the IonQ team marks a pivotal moment in SkyWater’s evolution,” said Thomas Sonderman, Chief Executive Officer of SkyWater Technology. “As the largest semiconductor foundry based in the U.S., SkyWater is already the partner of choice for advanced development and manufacturing services in both the public and private sectors as quantum computing shifts from research to manufacturing. Being part of IonQ will accelerate multiple engineering pathways for next-generation quantum chips, delivering speed, precision, and scale. Importantly, SkyWater remains fully committed to all of our semiconductor foundry customers and will continue as the quantum supplier of choice with an even broader set of quantum sensing and quantum networking solutions for our customers and partners.”
Operational Governance and Subsidiary Management
Following the close of the transaction, Thomas Sonderman will remain at the helm of SkyWater as its Chief Executive Officer, reporting directly to IonQ CEO Niccolo de Masi.
Under Sonderman’s continued leadership, the subsidiary will maintain its portfolio of Advanced Technology Services (ATS), Wafer Services, and Advanced Packaging Services. Additionally, the unit will expand its commercial offerings to include specialized atomic clocks, quantum interconnects, and quantum sensing hardware for external partners across the industry.
