IonQ, Inc. is an American technology company that specializes in the design, development and delivery of trapped-ion quantum computing systems. Leveraging individual ions as qubits, IonQ’s approach aims to combine high coherence times with universal gate operations, positioning its hardware as a leading platform for quantum applications in optimization, machine learning, simulation and cryptography. The company offers both on-premises systems and cloud-based access via major public cloud providers, enabling organizations to experiment with quantum algorithms at scale.
Founded in 2015 by physicists Christopher Monroe and Jungsang Kim, IonQ has its corporate headquarters in College Park, Maryland, with additional research and development facilities in Sunnyvale, California. The company went public in October 2021 through a business combination with dMY Technology Group, trading under the ticker IONQ on the New York Stock Exchange. Since then, IonQ has continued to expand its engineering team and strengthen its product roadmap to meet growing demand for quantum compute resources.
Under the leadership of Chief Executive Officer Peter Chapman, IonQ has introduced multiple generations of trapped-ion systems, including its Harmony and Aria platforms. These systems are made available through cloud portals such as Amazon Braket, Microsoft Azure Quantum and Google Cloud, allowing developers, academic researchers and enterprise users across North America, Europe and Asia to run quantum circuits without investing in dedicated hardware. IonQ also supports open-source software frameworks to foster an ecosystem of quantum application development.
With a focus on improving qubit counts, gate fidelities and system reliability, IonQ continues to advance its trapped-ion architecture through ongoing research partnerships and customer collaborations. The company’s strategy emphasizes turnkey quantum access, robust performance metrics and broad industry engagement as it seeks to accelerate the adoption of quantum computing across finance, pharmaceuticals, materials science and logistics.
