- What is quantum electrodynamics (QED) ?
It is the most accurate theory to describe light-matter interactions
- What is the aim of this website ?
This site is an introduction to QED for molecular systems
- Why is QED important ?
It is used to describe optical phenomena and has enabled many new discoveries
- How does QED differ to the classical methods ?
Both light and matter are quantised, i.e. a full quantum framework is employed
