Quantum Field Theory is one of the most popular topics in theoretical physics. Shortly it is called QFT. It is a theoretical framework to construct quantum mechanical model for subatomic particles and quasiparticles. In particle physics QFT have a role of giving quantum mechanical model of subatomic particles. But it also give a model of quasiparticles in condensed matter physics.
The superiority of quantum field theory is that it combines special theory of relativity, quantum mechanics and Newtonian classical mechanics.
Quantum field theory treat particle as the excited state of underlying field. Quantum electrodynamics is one of the successful result of Quantum field theory.
