IonQ is a quantum computing company that develops and commercializes systems based on trapped-ion architecture, in which individual atomic ions serve as qubits manipulated by lasers. Publicly traded on the NYSE under the ticker IONQ, the company describes itself as a leading quantum platform company and builds on decades of underlying academic research to move trapped-ion systems from the lab toward practical use.
IonQ's trapped-ion approach is notable for high gate fidelity and long qubit coherence times, which the company cites as advantages for stable quantum operations. Its product line includes successive generations of quantum systems such as Harmony, Aria, Forte, and Tempo, and it offers a full-stack platform spanning quantum computing, quantum networking, quantum security, and quantum sensing. Customers most commonly access IonQ systems through the cloud, with availability via Amazon Braket, Microsoft Azure, and Google Cloud, and support for popular quantum programming tools.
The company works with a range of enterprise and government customers and partners, with publicly referenced names including Hyundai, Airbus, AstraZeneca, and U.S. national laboratories and agencies, alongside technology partners such as NVIDIA, Dell, and Lockheed Martin.
As a public company, IonQ reports financial results and pursues an expanding roadmap across computing, networking, and sensing. Its positioning centers on delivering accessible, cloud-available quantum hardware and a broad quantum technology portfolio.
