Quantum optics could guard against GPS spoofing

Physics Today reports that classical methods of verifying position can be easily fooled by GPS spoofing, but quantum states of light could authenticate a receiver's location. The catch is practical: the scheme only works if systems are fast enough and losses are low enough, which remains the main bottleneck to real-world deployment.

Why now: Rising concern over GPS spoofing is drawing attention to quantum position verification as a potential fix.
