Host Maria Varmazis and Eddy Zervigon, CEO of Quantum XChange discuss how quantum computing is going to impact the space industry. Unlike with previous technologies and advancements, the space industry is taking a more proactive approach to quantum computing as stakeholders invest in and manage rapidly-accelerating cyber and operational risks. Subscribe and listen to the conversation now. Space after quantum. This week on T-Minus: Space-Cyber Briefing: we look at how the space sector is preparing itself for quantum computing. While practical quantum computing has long seemed just over the horizon, governments and commercial space operators alike are now actively preparing for the day when quantum computing becomes capable of breaking widely used public-key cryptography.

For decades, quantum computing has largely been viewed as an emerging technology that remained years away from practical deployment. Today, rapid advances in hardware, software, and investments have shifted this conversation from whether quantum computing will reshape the industry to how quickly organizations need to start preparing for quantum’s arrival. Space systems face a unique challenge because many satellites are designed to operate for decades after launch, often with limited opportunities to update their onboard software or hardware. Unlike terrestrial infrastructure, replacing vulnerable cryptography on orbit can be difficult, or in some cases, impossible. If quantum-capable adversaries are able to compromise the cryptographic systems that protect satellite communications, they could potentially intercept sensitive communications, spoof commands, manipulate telemetry, or inject malicious software updates into trusted systems.
