Stealth quantum sensors unlock possibilities anywhere GPS doesn’t work

A University of Waterloo PhD student and entrepreneur has commercialized ultra-sensitive quantum sensors capable of detecting single photons, enabling unprecedented precision in extreme environments where GPS fails. The startup, Phantom Photonics, leverages quantum technology to filter background noise, offering stealthy, high-accuracy sensing for underwater, space, and other GPS-denied applications. CEO Alex Maierean, a part-time IQC researcher, transitioned academic work into a viable business after identifying commercial potential in her quantum sensor research. These sensors could revolutionize navigation, defense, and exploration by providing reliable data in conditions where traditional systems struggle, from ocean depths to deep space. The innovation reflects accelerating commercial interest in quantum tech, with Waterloo’s entrepreneurial ecosystem driving real-world applications from lab breakthroughs.
