theoretical framework combining classical field theory, special relativity, and quantum mechanics
Quantum field theory is a framework that combines quantum mechanics with Einstein's theory of relativity to describe how fundamental particles and forces interact. It matters because it provides our most powerful and accurate way of understanding the behavior of nature at the smallest scales, from atoms to the particles that make up light and matter.

Encyclopedic overview
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines field theory, special relativity and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. The current Standard Model of particle physics is based on QFT.
Despite its extraordinary predictive success, QFT faces ongoing challenges in fully incorporating gravity and in establishing a completely rigorous mathematical foundation.
