4 Takeaways: How Quantum Technology Is Beginning to Reshape the Future of Space Systems

Quantum technology is advancing faster than many space organizations anticipated, and its emerging capabilities are beginning to influence how agencies and operators think about navigation, sensing, security and mission resilience.

In a recent podcast, Dr. Kelly Backes, lead quantum physicist at MITRE, outlined why Space ISAC launched its Quantum Community of Interest, how the sector can prepare for quantum integration and which technologies are most likely to matter over the next decade.

Read our top four takeaways from our conversation with Backes, or listen to the full episode.

Takeaway 1: Quantum is advancing rapidly, and space missions must begin preparing now.

Space systems are designed, procured and operated on timelines that stretch a decade or more – which means planning must account for emerging technologies well before they fully mature.

“In space, we don’t really have the luxury of waiting until something’s fully mature before we start paying attention,” Backes said. “Quantum is no longer this far-off research topic that’s destined to remain in the realm of the laboratory forever.”

Because missions operate in unforgiving environments and require extreme resilience, operators need early awareness of which quantum capabilities may become relevant within five to ten years, Backes said.

Many technologies being discussed today could align with that window. “If a class of technologies could start to matter in five to ten years, the planning window is now,” she said.

Space ISAC’s new Quantum Community of Interest, launched with support from MITRE, is designed to help organizations understand both the opportunities and the limitations: what’s real, what’s noise, and what needs long-term investment, Backes said.

Takeaway 2: Beyond computing, sensing and timing will bring significant quantum advantages to the space sector.

Quantum is not a single technology or development track, Backes noted.

“When people hear the word quantum, they often jump straight to quantum computing, and that’s understandable because it gets so much attention and there’s so much fantastic research being done in that space,” Backes said. “But quantum covers a huge set of technologies, and this huge set of technologies is at very different stages of maturity.”

Many are already familiar. Atomic clocks, for instance, “are fundamentally quantum,” and have been flying on spacecraft since the 1960s and integrated into GPS since the 1970s, Backes said. Their next-generation variants promise longer time holdover and improved resilience in GPS-denied environments, she said.

Sensing applications are also progressing quickly. Quantum inertial sensors, atomic magnetometers and magnetic navigation (MagNav) systems can improve onboard measurements and situational awareness without relying on external signals – a major benefit when operating through jamming, interference or degraded environments, she added.

Backes highlighted the dual utility of these sensors. They enable navigation, but they also support the mapping required for magnetic and gravitational reference systems. “There are a number of quantum sensors that are promising candidates to perform the magnetic mapping,” she said, with similar promise for gravitational mapping and Earth observation.

Takeaway 3: Quantum won’t replace classical systems – it will enhance specialized mission needs.

Backes addressed one of the most common misconceptions she encounters: “People often think that quantum sensors are going to come in and take over everything. We won’t need antennas anymore,” she said. “And that’s not true.”

Quantum systems will be highly impactful in niche mission areas – not universal ones, Backes said. Their value lies in enabling measurements that classical sensors cannot achieve or giving operators more tunability and flexibility in specific environments, she said.

Current quantum devices may appear large or power-intensive because they are still mid‑TRL. “We’re still tweaking them,” Backes said. But many of their subcomponents already have rugged, space-qualified analogs thanks to decades of atomic clock development. As packaging improves, these systems could become far more deployable across missions that require precision, adaptability and resilience, she said.

Takeaway 4: Collaboration across academia, industry and government is essential for quantum adoption.

Quantum technologies will only reach orbit if all parts of the ecosystem work together, Backes emphasized. Academia takes early risks on unconventional ideas, organizations like MITRE help evaluate mission potential and industry determines manufacturability and deployment, she said.

“If anybody drops the ball…the technology will never make it out into the field,” she said.

The Space ISAC Quantum Community of Interest aims to connect emerging quantum researchers with space operators who understand real system needs – environmental constraints, sensing gaps, bandwidth requirements and operational vulnerabilities, Backes said. This insight is indispensable, she stressed. “The boots on the ground in the space industry are critical to my understanding of what the real needs are.”

By bridging these perspectives, the community hopes to guide how quantum technologies should be designed, ruggedized and tested for actual missions, ensuring they address meaningful operational challenges rather than hypothetical ones, Backes said.
