Resumen:
In this paper, we deal with the situation in which the unknown state of a quantum system has to be estimated under the assumption that it is prepared obeying aknown set of symmetries. We present a system of equations and an explicit solutionfor the problem of determining the MaxEnt state satisfying these constraints. Ourapproach can be applied to very general situations, including symmetries of thesource represented by Lie and finite groups.
