"thin film gold deposited onto glass chip/ ion beams focused carving 100s slits acting as artificial meta-atoms... with light incoming, metacrystal identifies subtle quantum differences in light's coherence/ guides them down separate pathways... no millions of complex measurements/ cryogenic detectors... new class of resilient, room-temperature quantum materials accelerating deployment of: quantum computers, secure communications, high-efficiency solar cells, optical sensors"
