Quantum computing firm IonQ is doubling down on its ambitions in secure communication. On Wednesday, the Maryland-based company announced a deal to acquire Capella Space, a satellite imaging firm known for its synthetic aperture radar (SAR) technology, in a move designed to supercharge its push into quantum networking.

The acquisition marks a pivotal moment for IonQ, as it shifts from primarily offering quantum computing solutions to developing a space-based quantum key distribution (QKD) network. QKD is seen as essential for enabling unhackable communication channels in a future where classical encryption could be rendered obsolete by quantum computers.

Capella, based in San Francisco, operates four commercial satellites that collect high-resolution X-band SAR imagery, useful for intelligence, disaster response, and maritime surveillance. The company has additional satellite launches planned for this year, which will expand its imaging capabilities and support IonQ’s space-to-space and space-to-ground QKD efforts.

According to IonQ CEO Niccolo de Masi, the acquisition will “deepen and accelerate IonQ’s quantum networking leadership” by combining Capella’s satellite infrastructure with IonQ’s quantum technologies. “We have an exceptional opportunity to accelerate our vision for the quantum internet,” he said.

In addition to providing satellite assets, Capella also brings a valuable facility security clearance, enabling closer collaboration with U.S. defense and intelligence agencies—key customers for quantum-secure communications.

The Capella deal is the latest in a string of strategic moves by IonQ. Earlier this year, it acquired Qubitekk, a specialist in quantum networking, and Lightsynq Technologies, a startup founded by former Harvard researchers focused on quantum memory. IonQ has also signed a memorandum of understanding with Intellian Technologies, a satellite hardware manufacturer, to explore integrating quantum networking into future satellite ground systems.

Capella CEO Frank Backes echoed the enthusiasm, saying the integration of Capella’s radar imaging with IonQ’s quantum computing would enhance global defense and commercial missions through “ultra-secure environments.”

The transaction, expected to close in the second half of 2025 pending regulatory approval, continues a trend of quantum-tech consolidation as players position themselves to meet anticipated demand for secure communications in both government and private sectors. As cyber threats grow and classical encryption ages, the ability to offer end-to-end quantum-secure channels—especially via space infrastructure—may become a competitive necessity.

IonQ’s aggressive strategy has drawn investor interest, with its stock gaining momentum in recent weeks. As the quantum industry matures, vertical integration—spanning hardware, software, and infrastructure—is becoming increasingly critical.

If successful, IonQ’s vision for a global quantum-secure network could reshape how sensitive data is protected and transmitted across borders, laying the groundwork for a new era of secure, quantum-powered communication.
