Quantum Computing Could Break Satellite Encryption — Here’s Why

Quantum computing may still be years away from breaking today’s encryption, but the security problem starts now. In this SpaceIQ Q2 2026 conversation, Space Capital Founder and CEO Chad Anderson sits down with Eddie Zervigon, CEO of Quantum Exchange, to discuss why satellites are uniquely exposed to the emerging quantum threat. Zervigon explains “Harvest Now, Decrypt Later,” where adversaries collect encrypted data today with the expectation that future quantum computers will be able to decrypt it. For satellites designed to remain in orbit for 10 to 15 years, upgrading security after deployment is not a realistic option. They discuss the shift toward quantum-safe encryption, new federal migration deadlines, the importance of building crypto-agility into satellite architecture, and why post-quantum cybersecurity is becoming both a critical infrastructure requirement and an emerging investment category. As more of the global economy depends on GPS, communications, defense systems, and infrastructure in orbit, securing space against future quantum attacks is becoming an immediate priority.
