July 16, 2024 -- QuantCAD LLC, a physics start-up operating in Iowa City, IA and Chicago, IL, was selected by NASA to advance quantum sensing with a Small Business Innovation Research (SBIR) Phase II contract. NASA plans to use the quantum sensor developed by QuantCAD to investigate the origins of water on exoplanets.

Over the next two years, QuantCAD will refine a prototype quantum sensor for measuring the isotopic composition of water - specifically the ratio of deuterium to hydrogen. The proposed device features high sensitivity and significantly reduces the weight typically associated with conventional sensors that use technology similar to magnetic resonance imaging (MRI) tools. In addition, the QuantCAD device can operate for extended periods in challenging environments as it does not require consumables. Ivan Viti, Quantum Systems Engineer at QuantCAD and PI for the Phase I noted “Our technology marks a turning point in the ability to trace water sources across the solar system, unlocking new possibilities for pinpointing water origins, crucial for future missions.”

The sensor limits the effects of diffusion noise on the optical signals using spin centers embedded within the walls of a container. QuantCAD has calculated a sensitivity improvement of up to 100,000x compared to systems using MRI-like technology classical NMR systems. “Our aim is to decipher the origins of solar system water, a pivotal step that promises to unlock profound insights into the early evolution and composition of the moon and the inner Solar System” explains Fabrizio Sgrignuoli, QuantCAD Physicist and PI for Phase II. This low-cost, robust to rough environments, lightweight, and small footprint technology represents a significant forward step toward sustainable space exploration programs.

This is the second Phase II contract awarded to QuantCAD by NASA in the area of quantum sensing. NASA has also selected QuantCAD for a third Phase I award which will expand their sensing capabilities in extreme environments. The increasing support validates QuantCAD’s approach and expands their ability to innovate within the aerospace sector. QuantCAD founder and CEO, Jennifer Flatté observed, “In an era when women- and minority- owned businesses still struggle for equal access, these contracts allow our company to continue its mission to advance low-noise quantum sensing while also spearheading diversity and inclusion in the workspace.”
