Quantinuum
Quantinuum (QNT) is a publicly traded Trapped-Ion Qubits company founded in 2021 and based in Broomfield, United States.
Quantinuum was founded in 2021 and is headquartered in Broomfield, United States. The company manufactures commercially available trapped-ion quantum computers (the H-Series, including the H1 and H2 systems with 56 physical qubits) and operates quantum software platforms including InQuanto (a computational chemistry platform) and TKET (an open-source circuit optimizer compatible with multiple hardware backends). Revenue is generated through cloud and on-premise deployments of quantum hardware to enterprises including JPMorgan Chase, BMW, and Airbus, and through licensing of software platforms. As of September 2026, Quantinuum has raised $2.43 billion in total capital, including a $100 million federal grant from the CHIPS Act announced in September 2026.
Quantinuum is one of the few companies operating commercially available trapped-ion quantum computers at scale, with the H2 system achieving a quantum volume of 33,554,432 and the highest commercially available two-qubit gate fidelity. The $100 million CHIPS Act award signals US federal investment in domestic quantum hardware manufacturing and aligns with the Department of Energy's 2028 fault-tolerance milestones. The company's open-source TKET compiler and InQuanto platform have established broad adoption in academic and commercial quantum software development, positioning it across both hardware and software layers of the quantum stack.
