Christopher McFadden describes an alternate way of using quantum sensors to navigate in Australia unveils jam-proof quantum tech that’s 50 times more accurate than GPS:
"Instead of relying on satellites, Q-CTRL’s system can read the Earth’s magnetic field, which varies slightly depending on location (like a magnetic fingerprint or map). The system can determine where you are by measuring these variations using magnetometers.
This is made possible using the company’s proprietary quantum sensors, which are incredibly sensitive and stable. The system also comes with special AI-based software, which filters out interference like vibrations or electromagnetic noise (what they call “software ruggedization”).
Note that the headline is misleading:
"Moreover, the company reports that its quantum GPS was 50 times more accurate than traditional GPS backup systems (like Inertial Navigation Systems or INS). The systems also delivered navigation precision on par with hitting a bullseye from 1,000 yards.
Even when the equipment was mounted inside a plane, where interference is much worse, it outperformed existing systems by at least 11x."
This is just wrong, see above:
This is the first time quantum technology has been shown to outperform existing tech in a real-world commercial or military application, a milestone referred to as achieving “quantum advantage.”"
