Quantum optics proposed as defense against GPS spoofing

A Physics Today article explains that classical position verification methods are easy to fool, and quantum states could instead authenticate a receiver's location. The catch: such systems only work if they are extremely fast and low-loss, which remains the main practical bottleneck for real-world deployment against GPS spoofing.

Why now: GPS spoofing attacks are a growing security concern, making quantum-based location verification newly relevant.
