Quantum field theory extends quantum mechanics, which deals with particles, to a generalized domain having infinite degrees of freedom.
Quantum field theory is compatible with the theory of relativity, while quantum mechanics is not. Quantum field theory attempts to explain and describe the interactions between an electromagnetic field and charged particles in what is sometimes called quantum electrodynamics.
