DARPA Selects Quantinuum for Quantum Benchmarking Initiative Phase B

On November 7, 2025, Quantinuum, a global leader in quantum computing, was officially chosen by the Defense Advanced Research Projects Agency (DARPA) to progress to Phase B of their Quantum Benchmarking Initiative (QBI). This marks a significant milestone in DARPA's efforts to assess the technical feasibility of making utility-scale quantum computers available by 2033.

The Journey So Far

The QBI is a multifaceted program aimed at determining whether a fully functional utility-scale quantum computer can be developed within the next decade. This selection comes after a Phase A, lasting six months, where Quantinuum created a detailed conceptual design for a utility-scale system named 'Lumos'. This system is now at the forefront of discussions regarding the future of quantum computing.

Quantinuum's public roadmap aims for the release of 'Apollo', a fully fault-tolerant universal quantum computer, by 2029. With Lumos, the company intends to advance its systems considerably throughout the decade of the 2030s. Dr. Rajeeb Hazra, the CEO of Quantinuum, expressed optimism about the future, stating, "This selection reflects the strength and maturity of our roadmap and the work our teams have already accomplished. Lumos extends our roadmap into the next decade and provides DARPA with a concrete, risk-mitigated pathway to achieve utility-scale quantum computing by 2033."

What’s Next for Quantinuum

Phase B will involve a one-year performance evaluation conducted by DARPA's Test and Evaluation team. During this phase, Quantinuum will develop a rigorous R&D roadmap for Lumos, validating its technical assumptions, verification methods, and scaling plans to meet the ambitious 2033 target.

In addition to this announcement, Quantinuum completed the implementation of its latest high-performance system, named 'Helios'. Designed to meet tight timelines, Helios boasts the highest fidelity physical and logical qubits of any commercial system to date. Its advanced software stack, which includes a modern high-level programming language, aims to accelerate the adoption of quantum computing across various industries. Helios has already demonstrated its capabilities by simulating high-temperature superconductivity and magnetism at unprecedented scales, tapping into applications highly relevant to industrial needs.
