Agreement and Plan of Merger regulatory

"entered into an Agreement and Plan of Merger with SkyWater"

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

vertically integrated full-stack quantum platform technical

"Creates the Only Vertically Integrated Full-Stack Quantum Platform Company"

fault-tolerant quantum computing technical

"Accelerates IonQ’s Fault-Tolerant Quantum Computing Roadmap"

Fault-tolerant quantum computing is the ability of a quantum computer to keep producing correct results even when its basic parts make mistakes, by detecting and fixing errors and using redundancy so the machine continues to work reliably. For investors, it matters because fault tolerance is the key to scaling quantum machines from experimental demos into practical, revenue-generating systems—think of it like having backups and automatic repairs that make a prototype road-ready and lower the technology’s commercial and technical risk.

Technology as a Service technical

"SkyWater’s Technology as a Service model empowers innovators"

Trusted Foundry technical

"SkyWater is a DMEA-accredited Category 1A Trusted Foundry"

A trusted foundry is a semiconductor manufacturing facility that has been vetted and authorized to make chips for customers with sensitive or classified requirements, often under government security rules and special oversight. Think of it as a certified workshop that follows strict controls over materials, designs and who can access them; for investors, its status affects access to defense or regulated contracts, supply-chain resilience and potential revenue tied to secure programs.

two-qubit gate fidelity technical

"In 2025, the company achieved 99.99% two-qubit gate fidelity"

Two-qubit gate fidelity measures how accurately a quantum computer performs a basic operation that links two quantum bits (qubits). Think of it like the success rate of a two-person handshake that must be precise for a larger task; higher fidelity means fewer errors, better chances of running useful algorithms, and lower cost to correct mistakes. Investors watch it because higher fidelity signals more reliable hardware and faster progress toward commercially valuable quantum computing.
