The National Science Foundation has awarded $600,000 for a three-year collaboration led by Hyeongrak “Chuck” Choi of Stony Brook University and Bo-Han Wu of the University of Hawaiʻi at Mānoa. The researchers will study how distributed quantum sensors can coordinate and use quantum resources to detect weak, changing signals; the work is research, not a report of a finished system or demonstrated application.
The National Science Foundation has awarded $600,000 to researchers at Stony Brook University and the University of Hawaiʻi at Mānoa for a three-year project on quantum intelligent sensor networks. Co-led by Stony Brook assistant professor Hyeongrak “Chuck” Choi and Hawaiʻi assistant professor Bo-Han Wu, the research will examine how spatially distributed quantum sensors could coordinate to detect weak, changing signals.
The project began on June 1, 2026, according to the report by The Quantum Insider. Instead of treating each sensor as a separate device, the researchers will investigate whether connecting sensing nodes through entanglement and other quantum resources can improve how a network extracts information about signals that vary across space. The stated aim is to develop design principles for coordinated sensing systems, not to announce a completed network or a measured performance gain.
Choi will lead work on the network architecture and distributed platform. His team will use information-theoretic methods, including quantum Fisher information, to study sensing limits and how network layout, entanglement distribution, losses and noise may affect performance. Wu’s group will lead the continuous-variable quantum photonics work, including computational models and optimization methods for configuring entanglement, sensing parameters and connections for specific tasks.
The researchers also plan to examine quantum error-correction strategies for dealing with noise and imperfections in devices. Initial work will focus on photonic systems using squeezed light and integrated optical components. The report says the team will develop principles that could later extend to other platforms, including diamond spin-based sensors. Grant support will also go toward student research, outreach, course materials and open-source software at both universities.
From Individual Sensors to Networks
Many sensing tasks involve signals that are weak, uneven or changing across a region. A network could, in principle, gather information from multiple locations rather than relying on one instrument. The project addresses a basic research question: whether coordinating quantum sensors can make useful information easier to extract, and what trade-offs arise from distributing quantum resources across a system.
The potential relevance spans areas the project identifies as possible long-term applications, including magnetic sensing, biomedical imaging and environmental monitoring, as well as quantum radar and communications. Those are prospective uses, not outcomes established by this grant announcement. The practical value will depend on whether the proposed architectures can operate despite loss, noise and device imperfections, and whether any performance advantages can be realized in real systems.
The collaboration also connects foundational research with training and shared research tools. Student projects, teaching materials and open-source software could help build expertise in quantum sensing and photonics at both institutions. The report does not specify the scale of those activities or give milestones for evaluating them.

A Three-Year Photonics Research Plan
The award is funded through the NSF’s Foundations of Emerging Technologies program, which supports foundational work in emerging technologies with potential long-term scientific and technological impact. The report describes the collaboration as a study of how distributed sensors might work as a coordinated system, rather than a project focused only on improving one standalone sensor.
Choi joined Stony Brook in 2024 as an assistant professor in electrical and computer engineering. His research includes quantum networking, error correction, sensing and photonics. The report also notes a separate Stony Brook AI Innovation Institute small grant to Choi on an AI-integrated quantum sensing topic. That work is described as related to the broader research direction, not as part of the NSF award.
For the NSF project, the first emphasis is on photonic architectures, including squeezed light and integrated optics. The report says the team intends to develop ideas that may apply to other sensor platforms, but it does not give a schedule for moving from models and design principles to a prototype.
“This project is about understanding how quantum sensors can work together as an intelligent system, rather than simply improving one sensor at a time.”

Performance and Applications Still Open
The report gives no experimental results, prototype specifications, performance benchmarks or comparison showing that a quantum intelligent sensor network already outperforms conventional approaches. The project is intended to study what can be extracted and how network design affects sensing; its results remain to be established.
It is also unclear which sensing task the researchers will prioritize after the initial photonics work, what technical milestones they have set, or how they will measure success over the three-year period. The named applications—including environmental monitoring, imaging, radar and communications—are described as potential long-term uses, not confirmed products or near-term deployments.

Research Moves Through Its Grant Period
The project is scheduled to run for three years from June 1, 2026. The next reported developments to watch for are the teams’ modeling and optimization results, findings on the effects of noise and loss, and any evidence that network designs can be tested beyond theoretical analysis. The source does not provide dates for publications, prototypes or interim reports.
Student research, outreach, course materials and open-source software are also part of the planned work. Further updates would be needed to establish what tools are released, what results the teams obtain and whether the proposed design principles can be extended beyond the initial photonic systems.
