Quantinuum Unveils 2030 Roadmap for Fault-Tolerant Quantum Computing

Quantum computing company Quantinuum has unveiled an ambitious roadmap toward achieving universal, fully fault-tolerant quantum computing by 2030.

The company outlined its strategy to scale quantum computing systems to thousands of physical qubits and hundreds of logical qubits while maintaining low error rates and integrating a full software stack.

This approach sets a path toward commercial quantum computers, which are the next essential step in the growing quantum market, which has the potential to be worth trillions of dollars.

Apollo Quantum Computer

At the heart of Quantinuum’s roadmap is its fifth-generation quantum computer Apollo, which the company said could deliver fully fault-tolerant, universal quantum computing. This next-generation system is designed to execute circuits with millions of gates, a development crucial for achieving scientific breakthroughs and driving commercial applications.

“We are the only company with a clear and demonstrable path that leverages quantum computing to tackle large-scale scientific and commercial applications,” said Quantinuum CEO Rajeeb Hazra.

The company’s quantum charge-coupled device (QCCD) architecture underpins the hardware development of its systems. This architecture allows for a universal gate set and the creation of high-fidelity physical qubits, which are essential for building reliable logical qubits.

Quantinuum has spent the last four years providing peer-reviewed research to validate the advances in its quantum systems, offering transparency and credibility to its claims.

Collaboration with Microsoft

Quantinuum has also shared key milestones achieved through its ongoing collaboration with Microsoft. Together, the companies created 12 logical qubits on Quantinuum’s System Model H2 quantum computer, tripling the number of logical qubits achieved earlier in 2024.

The companies have also demonstrated the first end-to-end scientific workflow using artificial intelligence (AI), high-performance computing (HPC) and logical qubits. This achievement brings the industry closer to realizing the vision of a hybrid classical-quantum supercomputer.

The partners have also integrated Quantinuum’s quantum chemistry software InQuanto with Microsoft’s Azure Quantum Elements platform. They have made a private preview of this integration available to customers.

Commercial Utility

Quantinuum’s roadmap also points to the growing commercial utility of quantum computing, as the company prepares to support hundreds of logical qubits in future systems to support applications such as finance, chemistry and computational biology.

“Our roadmap draws a direct line to hundreds of logical qubits, at which point quantum computing will outperform classical computing in solving a broad range of scientific problems," said Hazra.
