Quantinuum is an integrated quantum computing company formed by the 2021 merger of Honeywell Quantum Solutions and Cambridge Quantum. It builds trapped-ion (QCCD) quantum computers — the H1, H2, and Helios System Models — and develops the full software stack that runs on them: the Nexus cloud platform, the TKET quantum compiler, the InQuanto computational chemistry package, the lambeq quantum natural language processing toolkit, the Guppy quantum programming language, the Selene emulation framework, and the Quantum Origin verifiable randomness service. Programmatic access to Quantinuum systems is delivered through the Nexus platform (Python client qnexus plus a REST/OpenAPI surface) and via partner clouds; circuits are described in OpenQASM 2.0 and the Quantum Intermediate Representation (QIR).
