This global quantum sensing market analysis and forecast reflects a developing market moving from early commercialization toward broader adoption. It is characterized by sustained growth and strong government demand. The market is estimated at approximately $470 million in 2025 and is projected to reach to $1.1 billion by 2028 (figure 1), representing average annual growth of 32%. Demand spans multiple technology platforms, applications, and end-use markets rather than a single dominant modality. Government, particularly defense, continues to shape overall market structure and trajectory, even as commercial participation expands; aerospace remains the leading commercial opportunity, with biosciences showing incremental growth.

Based on responses from 58 participants representing 47 distinct companies, the quantum sensing segment comprises a mixed company structure. Most respondent companies are privately held and generally focused on quantum sensing activities, while publicly traded respondents are more often diversified companies for which quantum sensing represents one component of a broader portfolio. Funding is also diversified, but government-supported research and development remains the most common source of support, alongside internal budgets and early end-user payments. The market nevertheless remains early stage, with more than one-third of respondents reporting no quantum sensing sales in 2025.

Technologically, the quantum sensing landscape remains varied. Rydberg atoms are most prevalent, followed by photons, neutral atoms and solid-state spins. Atomic clocks and magnetometers continue to anchor the application mix, with quantum imaging, photon detectors, inertial sensors, and gravimeters providing additional breadth.

The market is beginning to mature. Nearly a third of respondents report their primary technology as commercially available in 2025, rising to 58% by 2028.

From a revenue perspective, combined government segments (defense and civil) are projected to represent 47% of the quantum sensing market in 2028, with defense alone accounting for 35% and remaining the single largest individual segment. The commercial market is projected to reach 34% of total revenue in 2028, increasing from 25% in 2025, while academic participation declines modestly. Overall, the quantum sensing market exhibits credible growth anchored in government demand, expanding commercial participation, and varied technologies across established end-use ecosystems.
