New engineering blueprint outlines IonQ's end-to-end path to scaling fault-tolerant quantum computers to 10,000 physical qubits and beyond

IonQ (NYSE:IONQ), the world's leading quantum platform company, today announced a definitive, full-stack, buildable blueprint for scalable, fault-tolerant quantum computing. This publication sets a new standard for technical specificity and transparency in the quantum industry.

"The level of detail and completeness in our blueprint is a major global first and milestone for the quantum industry. IonQ's specificity sets a new standard and distinguishes IonQ with its tangibility, resting on capabilities our hardware has already demonstrated including 99.99% two-qubit fidelity and reliable ion transport. This historic work demonstrates precisely why IonQ is on track to be the first to unlock fully fault tolerant quantum computers - as we published in June 2025," said Niccolo de Masi, IonQ Chairman and CEO.

The technical paper describes IonQ's end-to-end architecture for fault-tolerant quantum computing, spanning compiler design and error correction to hardware, control systems, and ion movement. It outlines in detail how the company intends to move from today's systems to utility-scale quantum computers.

While IonQ's current systems lead in delivering real world solutions and business outcomes, achieving the next level of performance means moving past the constraints of noise, scale, and lack of modularity. IonQ's fault-tolerant framework creates a logical computing layer that actively detects and corrects errors in real time. The result is a practical path toward quantum computers capable of running longer, more complex computations with greater reliability.

The technical report describes the details behind IonQ's announced plans to scale toward large fault-tolerant systems and reflects the company's continued focus on performance, modularity, and commercial readiness. IonQ has tangibly shown today that for its current architecture, fault-tolerant quantum computing is an engineering challenge with a clear and achievable roadmap in the coming quarters.

IonQ was the first commercial company to link remote ion-traps using quantum entanglement; the first company to achieve 99.99% two-qubit gate fidelity; as well as the first company to convert quantum frequencies into telecom wavelengths; and it continues on its innovation track toward fault tolerant quantum computing.
