Entropy, quantum information and entaglement have recently acquried relevance in quantum field theory. On the other hand, we are interested in an infinite dimensional and covariant extention of previously developed MaxEnt methods. In this work, we will review the definition, properties and some problems regarding entropies in a quantum field theory context under different approaches. In particular, we will show how entropy is treated in the algebraic quantum field theory framework. Finally, we will also go through explicit computations for some elementary cases.
