Quantum optics proposed as defense against GPS spoofing

Researchers are exploring quantum position verification as a way to authenticate a receiver's location, addressing the vulnerability of classical GPS to spoofing attacks. According to a Physics Today report, quantum states could make location verification far harder to fake, but real-world deployment depends on building systems that are fast and low-loss — the main practical bottleneck currently holding the technology back.

Why now: Growing concern over GPS spoofing attacks is driving interest in quantum-based alternatives for secure position verification.
