Quantinuum has partnered with Oracle to deploy its Helios quantum computer on Oracle Cloud Infrastructure (OCI).

The multi-year agreement will allow customers to directly access the system via OCI’s forthcoming quantum service, providing them with “managed, secure access” to cloud-hosted quantum computing.

It will be the first quantum computer deployed by Oracle.

In a statement, Quantinuum said that by operating on-premises within OCI’s infrastructure, Helios will be able to integrate with existing OCI compute, networking, storage, identity, and data services under the same governance and access controls customers already use.

Oracle’s OCI quantum service is expected to combine Quantinuum’s development stack with support for open-source hybrid-programming frameworks, helping developers build, test, and refine quantum-classical applications more efficiently, the quantum firm said. The service will be previewed “in the coming months.”

“We believe the next phase of enterprise computing will be shaped by bringing quantum, AI, and high-performance computing together,” said Dr. Rajeeb Hazra, president and CEO of Quantinuum. “Deploying Helios inside OCI gives Quantinuum and Oracle an opportunity to create a unique deeply integrated environment for hybrid workloads, explore enterprise use cases with customers, and accelerate commercial adoption.”

Mahesh Thiagarajan, EVP of Oracle Cloud Infrastructure, added: “AI has changed what organizations can imagine, and we believe quantum computing can expand what they’re able to solve. By bringing Quantinuum’s Helios to Oracle Cloud Infrastructure, we want to give developers a practical and secure way to explore how quantum computing could complement their existing AI and HPC workloads on Oracle Cloud Infrastructure while improving compute efficiency and energy use.”

Quantinuum was founded in 2021 when Honeywell spun out its Quantum Solutions division and merged it with UK quantum computing startup Cambridge Quantum Computing. Honeywell owns a 54 percent stake in the company, and IBM is also an investor.

The company launched Helios in November 2025. Helios is a general-purpose quantum computer that allows developers to program quantum and heterogeneous classical computers in the same way, thereby enabling hybrid quantum capabilities to be combined in a single program.

In June 2026, Quantinuum debuted on Nasdaq at $68 per share, with its market cap topping $15.7bn.
