Quantum Physicists Found a New, Safer Way to Navigate

Quantum physicists are developing new navigation systems that could serve as safer alternatives to GPS, which is vulnerable to hacking. Researchers at Lockheed Martin, led by engineer Michael DiMario, have created a prototype quantum magnetometer that utilizes a synthetic diamond with nitrogen vacancy centers to detect magnetic anomalies in Earth's magnetic field. This device can measure both the strength and direction of magnetic fields, allowing for navigation without satellite communication, thus reducing hacking risks. The team has successfully tested the sensor in various transportation modes, aiming to eventually miniaturize it for broader applications. Additionally, physicist Azure Hansen at the National Institute of Standards and Technology is working on a quantum gyroscope that could provide more reliable rotational motion sensing, crucial for navigation in aviation and autonomous vehicles. These quantum sensors, while not expected to surpass GPS accuracy, could serve as effective backups, enhancing navigational safety across different modes of transport. The development of these technologies is ongoing, with hopes for market readiness in the coming years.
