About
IonQ is a College Park, Maryland-based quantum computing company that develops and operates trapped-ion quantum computers accessible via cloud API through Amazon Web Services, Microsoft Azure, and Google Cloud. IonQ's trapped-ion approach uses individual ytterbium atoms as qubits, cooled and suspended by electromagnetic fields, enabling higher qubit fidelity and longer coherence times than superconducting competitors. The company went public via SPAC merger in 2021 and trades on the NYSE, making it the first pure-play quantum computing company to go public. IonQ serves enterprise customers in pharmaceutical drug discovery, financial portfolio optimization, machine learning acceleration, and logistics using quantum algorithms that provide early advantage on specific problem classes. The company's Aria and Forte systems represent successive generations of increasing qubit count and error rates. IonQ competes with IBM Quantum, Google Quantum AI, and Quantinuum in the cloud-accessible quantum computing market and has built enterprise partnerships with Hyundai, GE Research, and Goldman Sachs.
