Abstract: The theory of Unimodular Gravity(UG) has been proposed as apossible solution of the cosmological constant problem yielding the same classical predictions than General Relativity (GR). In this talk I will construct the quantum formulation of the theory and show that the cosmological constant is still protected. Furthermore, some quantum effects in the presence of matter are also analyzed and compared with the ones from GR, showing that, so far, there is no way to distinguish between both theories.
