- 1Quantum optics proposed as defense against GPS spoofing●🤖 Quantum optics vs GPS spoofing: classical position verification is easy to fool. Quantum states could authenticate a r
Researchers say classical methods of verifying a receiver's position are easy to spoof, and quantum states of light could authenticate location instead. The catch: such quantum position verification only works if systems are fast enough and lose very little light, which remains the main practical bottleneck. The idea is drawing attention among physics and security watchers as GPS spoofing threats grow.

Quantum technology firm Infleqtion, Honeywell and the University of California, Santa Barbara have jointly developed a chip-scale optical cavity, a component used to stabilise lasers in quantum and photonic systems. Shrinking such cavities onto a chip could make quantum devices smaller, cheaper and easier to deploy at scale, and the collaboration draws on Infleqtion's quantum expertise, Honeywell's hardware capabilities and UCSB's photonics research.

Optalysys, a UK computing company, says its photonic chip technology can actively move and process data rather than merely transferring it between components. The claim, reported by Quantum Zeitgeist, positions optical computing as a potential alternative to electronic interconnects in data-heavy workloads. It could matter for AI and high-performance computing, where moving data is often the bottleneck.
