    "abstract": "We compare some recent computations of the entanglement of formation in\nquantum information theory and of the entropy of a subalgebra in quantum\nergodic theory. Both notions require optimization over decompositions of\nquantum states. We show that both functionals are strongly related for some\nhighly symmetric density matrices. We discuss the presence of broken symmetries\nin relation with the structure of the optimal decompositions.",
