"artificial meta-atoms: 100s slits carved into thin gold film deposited onto glass chip... size, shape, spacing act as statistical filter automatically identifying subtle quantum coherence differences in incoming light/ routes each state along separate pathways... photon rather than thermal-vibration-sensitive atom focus eliminates need for bulky cryogenic cooling to preserve quantum behavior... scalable quantum computing, ultra-secure communication networks, high-precision sensors, efficient renewable energy tech"
