In a major step toward realizing a quantum-secure internet, IonQ, a leading quantum computing and networking company, has announced it has entered into a definitive agreement to acquire Capella Space Corporation, a leader in advanced satellite signal platforms serving top-secret government and commercial applications.
This acquisition, expected to close in the second half of 2025 pending regulatory approvals, represents a bold move by IonQ to launch the world’s first space-to-space and space-to-ground quantum key distribution (QKD) satellite network. If successful, IonQ will become the first company to operate both a quantum computer and a quantum network in space.
The acquisition of Capella builds on IonQ’s recent momentum, following its purchases of Qubitekk (a quantum networking pioneer) and ID Quantique (a global leader in quantum-safe networking and detection systems), as well as a strategic memorandum of understanding with Intellian Technologies, a specialist in satellite communications infrastructure.
A Vision for the Quantum Internet
IonQ’s CEO, Niccolo de Masi, described the acquisition as a critical accelerator toward creating a secure, quantum-enabled 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. Through our acquisitions of Lightsynq and Capella, and our collaborations with partners like Intellian, IonQ is well-positioned to lead the next generation of quantum networking.”
QKD technology leverages the principles of quantum mechanics to generate encryption keys that cannot be intercepted, copied, or decoded without detection—making communications virtually immune to traditional cyberattacks. Until now, QKD deployment has largely been limited to terrestrial networks and short distances. By integrating Capella’s sophisticated satellite capabilities with IonQ’s advancements in quantum repeaters (via its Lightsynq acquisition), the company aims to achieve global, space-based quantum-secure communications.
Bringing Quantum Technology to Space-Based Operations
Capella Space’s CEO, Frank Backes, emphasized the transformative potential of the merger:
“Quantum technologies will revolutionize space-based operations by enabling ultra-secure communications between platforms. Capella’s proven satellite constellation, combined with IonQ’s quantum leadership, will create enhanced analytics, sensors, and communications security for commercial and defense missions alike.”
Strengthening Defense and Intelligence Capabilities
This strategic acquisition also reinforces IonQ’s growing role in the defense and intelligence sectors. The company has recently:
-
Signed a quantum networking contract with the Applied Research Laboratory for Intelligence and Security (ARLIS)
-
Partnered with the U.S. Air Force Research Laboratory (AFRL) to deploy quantum networking infrastructure in New York
-
Secured a $22 million collaboration with EPB in Chattanooga, Tennessee, to create the nation’s first combined quantum computing and networking hub
Through these initiatives, IonQ is positioning itself at the forefront of next-generation cybersecurity, defense technologies, and quantum networking innovation.
Why This Matters
The move to develop a space-based quantum network signals a new phase in both the quantum technology race and the evolving space economy. As cybersecurity threats escalate worldwide, governments and industries alike are seeking quantum-safe communication methods to protect critical data. Space-based QKD networks could underpin secure global communications, cloud computing, military operations, and even financial transactions in the near future.
IonQ’s strategy of integrating quantum technologies with satellite communications highlights a larger trend: the convergence of quantum computing, satellite technologies, and defense modernization. With this bold step, IonQ is not just innovating within quantum computing — it is reshaping the architecture of the future internet.
