Quantum electrodynamics
In particle physics,
quantum electrodynamics
(
QED
) is the
relativistic
quantum field theory
of
electrodynamics
. In essence, it describes how
light
and
matter
interact and is the first theory where full agreement between
quantum mechanics
and
special relativity
is achieved. QED mathematically describes all
phenomena
involving
electrically charged
particles interacting by means of exchange of
photons
and represents the
quantum
counterpart of
classical electromagnetism
giving a complete account of matter and light interaction.
