    "abstract": "We consider the classical algebra of observables that are diagonal in a given\northonormal basis, and define a complete decoherence process as a completely\npositive map that asymptotically converts any quantum observable into a\ndiagonal one, while preserving the elements of the classical algebra. For\nquantum systems in dimension two and three any decoherence process can be\nundone by collecting classical information from the environment and using such\nan information to restore the initial system state. As a relevant example, we\nillustrate the quantum eraser of Scully et al. [Nature 351, 111 (1991)] as an\nexample of environment-assisted correction. Moreover, we present the\ngeneralization of the eraser setup for d-dimensional systems, showing that any\nvon Neumann measurement on a system can be undone by a complementary\nmeasurement on the environment.",
