Scientists Create World's Smallest QR Code for Long-Term Data Storage

Scientists have successfully created the world's smallest QR code by etching a grid pattern into a thin ceramic layer using an ion beam. The microscopic code represents a breakthrough in data storage technology, offering an energy-efficient method for preserving information over extended periods. The ceramic-based approach could provide a durable alternative to traditional digital storage methods, as ceramic materials are known for their resistance to degradation and environmental factors over time.
