The basic laws of physics are based on arrangements that decide the relations among charged particles. Now researchers from the Heidelberg University have experimentally formed the arrangements of quantum electrodynamics using ultracold atoms. Researchers are planning for the detailed investigation of this complex physical theory with their experiments. Their discovery is considered a major step towards a platform developed from a string of properly connected building blocks for large-scale implementation of quantum electrodynamics in ultracold atoms. They hope it will open the doors to achieve future quantum technologies that can reproduce complicated physical events.
