Quantinuum Nexus is one of 9 APIs that [Quantinuum](https://apis.io/providers/quantinuum/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Quantum Computing, Cloud Platform, Job Submission, Compilation, and Project. The published artifact set on APIs.io includes API documentation.

Nexus is Quantinuum's all-in-one quantum computing cloud platform. It brokers access to Quantinuum H-Series hardware (H1, H2, Helios) and to partner backends including IBM Quantum and Amazon Braket, manages projects, teams, roles, quotas, credentials, and linked accounts, and orchestrates job submission, compilation, results retrieval, and circuit visualization. Nexus exposes a Python client (`qnexus`, Apache 2.0) and a REST/OpenAPI surface ("Nexus OpenAPI") covered by the platform's Authentication & Quotas documentation. Jobs are submitted as OpenQASM 2.0 or QIR programs and may be compiled and executed against Quantinuum systems or partner backends.
