Quantinuum was formed in 2021 through the merger of Honeywell Quantum Solutions (HQS) and Cambridge Quantum (CQ). Honeywell had been developing trapped-ion quantum computers since the early 2010s, achieving a breakthrough with the System Model H0 in 2020. Cambridge Quantum, founded in 2014 by renowned physicist Dr. Bob Coecke and others, specialized in quantum software, cryptographic tools, and quantum machine learning. The merger brought together the world's highest-fidelity quantum hardware with advanced software platforms like tket, a state-of-the-art quantum compiler, and the IronBridge cryptographic platform. In 2022, Quantinuum launched the H1-1 and H1-2 quantum processors with 20 qubits and record-breaking fidelity. The following year, the company unveiled the H2 processor with 32 qubits and a new architecture, achieving a quantum volume over 2 million. In 2023, Quantinuum announced a partnership with OpenAI to explore quantum-ML hybrid models, and in 2024, it opened a new research lab in Munich. The company has also made strategic acquisitions, including a quantum sensing startup in 2022. Quantinuum's revenue has grown steadily, exceeding $100 million in 2023, and it is privately held with strong investor backing from Honeywell and other venture capital firms. The company continues to expand its workforce, expecting to hire over 200 new employees in 2025. Each milestone reinforces Quantinuum's mission to bring practical quantum computing to market.
