Quantum mechanics evolved to describe the electromagnetic field itself. The first field theory is called quantum electrodynamics. It is considered to be a high precision theory and its success is claimed to have started right from the beginning. However, there is a story behind the story. Theoretical results and experimental results came along in good agreement while both being false. This happend more than one time, as Dr. Alexander Unzicker summarizes in this YouTube Video:
