Quantum Hall Effect's electrons moving in quantized steps, engineered for first time for photons

"photons lack electric charge so do not naturally respond to magnetic fields, making Quantum Hall Effect impossible to replicate with light... overcome using Frequency-Encoded Photonic Chern Insulator forcing light to act like electron in magnetic field... replacing/ calibrating measurement standards with light rather than electricity, more stable/ energy efficient quantum photonic computers, sensors utilizing quantization's precisely detecting any slight deviation (environmental disturbances) from its steps"
