IonQ has officially released Superion 256, a major step forward toward quantum computing innovation. Today, the company unveiled its sixth generation platform. IonQ also intends to display the industrial design of the Superion 256 at its Investor Day in 2026. This is what happens on the New York Stock Exchange. The Superion 256 will be the foundation for all future IonQ compute offerings, further solidifying the company’s leadership position in quantum computer development.
Furthermore, the transition from idea to reality was swift. Ion trapping took less than a year from initial design. So far, the company has built the first fully integrated 256-qubit quantum processing units at its subsidiary SkyWater. Engineers have even trapped ions in prototype systems already. The systems are being built simultaneously at several U.S. sites.
That has resulted in six tapeouts for the chip in the first half of 2026. Working with SkyWater’s quantum foundry, IonQ’s design cycle was reduced from nine months to two. Meanwhile the teams cranked out 12 times more wafer lots in six months compared to previous foundry partnerships.
Strategic Acquisitions Drive Quantum Computing Breakthrough
Specifically, IonQ’s Electronic Qubit Control (EQC) powers the system. This technology controls trapped-ion qubits through integrated chip electronics rather than laser systems. Therefore, standard semiconductor processes now manufacture the underlying qubit control. Notably, this same technology helped IonQ achieve a 99.99% two-qubit gate fidelity world record in October 2025. Additionally, the system fits into a standard server rack footprint. It requires no custom buildout and consumes less power than a GPU rack.
“Superion is the result of two strategic acquisitions coming together to deliver this historic milestone. Oxford Ionics enabled IonQ to control natural, trapped-ion qubits using standard electronics, and SkyWater unlocked the ability to manufacture at semiconductor costs and scale,” said Niccolo de Masi, Chairman and CEO of IonQ. “Quantum computing, like classical computing before it, ultimately scales most powerfully on a semiconductor foundation. Superion 256 is the first quantum computer platform designed to be built by the hundreds rather than one at a time. Every generation that follows will be designed, fabricated, and packaged similarly – creating unique upgradeability in our Superion platform.”
Superion Platform Scales to Millions of Qubits
Looking ahead, the Superion platform scales from 256 qubits toward millions of qubits. Each subsequent generation will expand on the same ions, qubits, and electronic control systems. Meanwhile, IonQ Superion 10K is already underway, integrating CMOS technology onto the chip. Importantly, SkyWater already manufactures this scaling technique at volume.
IonQ is simultaneously developing both the 256 and 10K generations. Today, the company’s first cryo-CMOS test chips for the 10K are on display at the New York Stock Exchange. This 10K generation will run IonQ’s Walking Cat architecture, published in April 2026. This blueprint outlines application compilation, error correction, and ion movement across chips. Ultimately, IonQ expects semiconductor-based control to cut cost-per-qubit by over 300 times.
“Superion marks the most important inflection point the quantum computing industry has yet seen. It accelerates our industry from one-off lab machines to quantum computers manufactured at scale with compelling unit economics and modest energy consumption,” said Chris Ballance, President of Quantum Computing at IonQ. “The step from 256 to 10K qubits is being delivered by integrating CMOS onto the chip – something the semiconductor industry has done many times and SkyWater does every day. CMOS integration is expected to reach full fault tolerance reality in a 2027 lab setting at IonQ, and manufacturable, commercial reality in 2028.”
Customer Orders Open Now for Superion 256
Currently, customers can order Superion 256, with deliveries scheduled for 2027. Notably, IonQ pre-sold its first Superion 256 system during the first quarter of 2026. Additionally, production-grade systems will run on IonQ’s cloud platform.
Since 2019, IonQ has deployed five generations of quantum computers, including its recent IonQ Tempo system. In April 2026, the company published the Walking Cat architecture. Then, in August 2026, IonQ reported breakeven quantum error correction using qLDPC codes on a Tempo test system, validating this architecture on real hardware.
