IonQ closes its $1.8 billion acquisition of SkyWater Technology on 31 July 2026, creating the first vertically integrated quantum-semiconductor company

IonQ (NYSE: IONQ) completed its acquisition of SkyWater Technology (NASDAQ: SKYT) on 31 July 2026 in a cash-and-stock transaction valued at approximately $1.8 billion, folding the largest exclusively US-based semiconductor foundry into a quantum computing platform for the first time. SkyWater shareholders received $15.00 in cash and 0.4883 shares of IonQ common stock for each share held at close. SkyWater will operate as a wholly owned subsidiary under its existing name, continuing to serve aerospace, defense, and commercial foundry customers.

What the deal gives IonQ

The acquisition addresses the single most persistent bottleneck in quantum hardware development: control over chip fabrication. IonQ's trapped-ion systems rely on its proprietary EQC (electronics-based qubit control) technology, which replaces laser-based qubit control with precision electronics manufactured on standard semiconductor chips, integrating all qubit-control components onto classical silicon. Owning a foundry lets IonQ run wafer iterations in-house rather than queuing behind external customers.

The combined entity gains:

• In-house wafer fabrication and advanced packaging at SkyWater's Bloomington, Minnesota facility
• Parallel wafer prototyping capability, expected to compress hardware iteration cycles
• Atomic clock and quantum interconnect production already in SkyWater's portfolio
• A domestic supply chain for quantum chip design through delivery, covering quantum computing, networking, security, and sensing

IonQ announced the definitive agreement in January 2026, citing the need to secure a fully scalable domestic supply chain and accelerate its fault-tolerant quantum computing roadmap.

Where this fits in the broader quantum hardware race

The SkyWater deal is the most direct intersection of quantum computing and conventional semiconductor manufacturing to emerge in 2026. It follows a year in which the quantum sector moved from debating whether error correction was achievable to benchmarking which companies achieve it most efficiently.

QuEra demonstrated 96 verified logical qubits from 448 physical atoms using a high-rate [[16,6,4]] code, published in Nature in January 2026 - doubling the prior record within 13 months. Microsoft unveiled its Majorana 2 processor at Build 2026 in June, reporting qubit coherence times exceeding 20 seconds - more than 1,000 times longer than its aluminum-based predecessor - after replacing aluminum with lead in the superconducting material stack. Rigetti's Cepheus-1, a 108-qubit processor at 99.5% two-qubit fidelity, reached general availability on Rigetti Quantum Cloud Services and was simultaneously listed on Microsoft Azure Quantum and AWS Braket.

Against that backdrop, IonQ's move is a supply-chain bet: the company that controls its own fab can iterate faster than rivals dependent on third-party foundries.

What SkyWater brings to the table

SkyWater is not a leading-edge logic foundry. Its strength lies in specialty process technologies - compound semiconductors, superconducting materials, and advanced packaging - that map directly onto quantum chip requirements. IonQ reported $130 million in full-year 2025 revenue, a 202% year-over-year increase, making it the first quantum computing company to exceed $100 million in GAAP annual revenue. That revenue base, combined with SkyWater's existing government and defense customer relationships, gives the combined company a credible path to funding continued hardware development without relying solely on equity markets.

The deal also signals a structural shift: quantum computing is no longer purely a physics problem. It is increasingly a manufacturing problem, and the companies that solve it at the fab level may define the next phase of the hardware race. Watch for IonQ's first disclosure of wafer iteration timelines under unified ownership, and for whether other quantum hardware firms respond with their own foundry partnerships or acquisitions.
