IonQ (NYSE: IONQ) published a technical report detailing its engineering approach to scaling fault-tolerant quantum computers to 10,000 physical qubits and beyond. The company released the document on arXiv, describing an end-to-end architecture spanning compiler design, error correction, hardware, and control systems.

The technical paper outlines how IonQ plans to transition from current quantum systems to utility-scale quantum computers. The company's fault-tolerant framework creates a logical computing layer designed to detect and correct errors in real time, according to the press release.

"The level of detail and completeness in our blueprint is a major global first and milestone for the quantum industry," said Niccolo de Masi, IonQ Chairman and CEO.

IonQ reported achieving 99.99% two-qubit gate fidelity in 2025, which the company described as a world record in quantum computing performance. The company also stated it was the first commercial entity to link remote ion-traps using quantum entanglement and to convert quantum frequencies into telecom wavelengths.

The College Park, Maryland-based company operates quantum computing services through major cloud providers and maintains operations in multiple countries including California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom.

IonQ's current customer base includes Amazon Web Services and AstraZeneca, with applications spanning drug discovery, materials science, financial modeling, logistics, cybersecurity, and defense sectors.

The technical roadmap document is available through arXiv and represents what the company characterized as a new standard for technical specificity and transparency in the quantum computing industry.
