IonQ has announced plans to launch the world’s first quantum-secure communications network in space, marking a significant expansion of its quantum networking ambitions.
To advance this vision, IonQ agreed to acquire Capella Space, a provider of high-resolution synthetic aperture radar (SAR) satellite imagery and secure sensing platforms for commercial and government missions. The acquisition, expected to close in the second half of 2025, will support IonQ’s development of a global quantum key distribution (QKD) network spanning space-to-space and space-to-ground links.
This move builds on IonQ’s recent momentum in quantum networking, including acquisitions of Qubitekk and ID Quantique, and a memorandum of understanding with Intellian Technologies for satellite communication solutions. With Capella’s space-based signal capabilities and Lightsynq’s long-distance photonic repeaters, IonQ aims to overcome distance limitations of terrestrial QKD systems and establish a secure global backbone for the future quantum internet.
“We have an exceptional opportunity to accelerate our vision for the quantum internet, where global Quantum Key Distribution will play a foundational role in enabling secure communications,” said Niccolo de Masi, CEO of IonQ.
- Strategic Acquisition: Capella Space will become a wholly owned subsidiary of IonQ, contributing satellite sensing, secure communications infrastructure, and ISR capabilities.
- Quantum in Orbit: IonQ plans to become the first company to host both a quantum network and quantum computer in space.
- Expanded Partnerships: Follows IonQ’s $22M collaboration with EPB and contracts with U.S. Air Force Research Laboratory (AFRL) and ARLIS.
- Secure Global Connectivity: IonQ’s QKD roadmap aims to ensure encryption keys are unbreakable and untraceable, even in space-based scenarios.
- Leadership Transition: Capella CEO Frank Backes will lead IonQ’s new quantum-space initiatives following the deal’s closure.
- Capella Space, headquartered in San Francisco, California, was founded in 2016 by Payam Banazadeh, a former NASA Jet Propulsion Laboratory engineer, and William Walter Woods. The company’s mission is to provide reliable, high-resolution Earth observation data through a constellation of Synthetic Aperture Radar (SAR) satellites, enabling 24/7, all-weather imaging capabilities. Capella’s SAR technology allows for the penetration of clouds and darkness, offering consistent monitoring of the Earth’s surface regardless of weather conditions or time of day. This capability is crucial for applications in defense, intelligence, environmental monitoring, and disaster response.
- Since its inception, Capella has achieved several milestones, including the launch of “Denali,” the United States’ first commercial SAR satellite, in 2018, followed by “Sequoia” in 2020, which demonstrated rapid and cost-effective production of high-quality SAR imagery. The company has continued to expand its satellite constellation with the deployment of the “Whitney” and “Acadia” series, enhancing imaging capacity and revisit rates. Capella has secured significant funding, raising approximately $250 million in equity and debt financing to date, with notable investments from Canaan Partners, Data Collective, Pear VC, and Spark Capital. These advancements have positioned Capella as a leading provider of SAR data, supporting various government and commercial clients worldwide.
