Jun Ye Awarded 2025 AB Nexus Grant for Quantum-Focused Research Collaborations
Using quantum sensing to detect pneumonia and asthma in children.
JILA and NIST Fellow and Â鶹Ãâ·Ñ°æÏÂÔØ physics professor Jun Ye has been awarded a prestigious 2025 AB Nexus seed grant for his pioneering work in quantum sensing technologies. The grant, part of a $750,000 funding initiative supporting interdisciplinary research between Â鶹Ãâ·Ñ°æÏÂÔØBoulder and the Â鶹Ãâ·Ñ°æÏÂÔØAnschutz Medical Campus, will help Ye and his collaborators develop a revolutionary breath test to diagnose respiratory illnesses in children.
Partnering with Dr. Lilliam Ambroggio of Â鶹Ãâ·Ñ°æÏÂÔØAnschutz, Ye’s team is harnessing the precision of quantum optics and advanced laser systems to analyze molecular signatures in exhaled breath. The goal: to rapidly and non-invasively distinguish between bacterial pneumonia, viral infections, and asthma—conditions that often present similarly but require vastly different treatments.
The project exemplifies the mission of AB Nexus, which was launched in 2020 to foster cross-campus collaborations that tackle complex health challenges. This year’s grant cycle emphasized quantum-enabled health research and support for early-career investigators. Ye’s project was one of two quantum-focused initiatives selected for $300,000 in seed funding.
Ye’s work continues JILA’s tradition of applying fundamental physics to real-world challenges. If successful, the breath test could eventually be adapted into portable devices for clinical use, offering a powerful new tool for pediatric care.
