Quantum Field Theory (QFT) is the mathematical framework that has been developed to describe the quantum theory of matter fields in interaction on a given space-time manifold together with a prescribed metric which can be curved. Indeed, when in the end of ninenteenth century physics seemed to be close to provide a very good deterministic explanation of all observed phenomena, Lord Kelvin identified “two clouds” on “the beauty and clearness of the dynamical theory”.

We will also mention a few points of fundamental importance for the physical interpretation of the theory. “For many decades quantum theory was regarded primarily as a mathematical description of phenomenal accuracy and reliability, capable of explaining the shapes and behaviours of molecules, the workings of electronic transistors, the colours of nature and the laws of optics, and a whole lot else. The remitted wave is likewise an electromagnetic wave with the identical frequency and speed as before. In the theory of quantum communication processes (see Channels in Quantum Information Theory; Optimal Cloning of Quantum States; ... To extend the definition to more general C*-algebras and states on them, one has to face the fact that C*-algebras may have no nontrivial C*-subalgebras. When applying the principles of QFT to GR one runs into a problem: QFT necessarily needs a classical metric in order to define a quantum field.
