    "abstract": "The protection of the coherence of open quantum systems against the influence\nof their environment is a very topical issue. A scheme is proposed here which\nprotects a general quantum system from the action of a set of arbitrary\nuncontrolled unitary evolutions. This method draws its inspiration from ideas\nof standard error-correction (ancilla adding, coding and decoding) and the\nQuantum Zeno Effect. A pedagogical demonstration of our method on a simple\natomic system, namely a Rubidium isotope, is proposed.",
