    "abstract": "We study the problem of driving an unknown initial mixed quantum state onto a\nknown pure state without using unitary transformations. This can be achieved,\nin an efficient manner, with the help of sequential measurements on at least\ntwo unbiased bases. However here we found that, when the system is affected by\na decoherence mechanism, only one observable is required in order to achieve\nthe same goal. In this way the decoherence can assist the process. We show\nthat, depending on the sort of decoherence, the process can converge faster or\nslower than the method implemented by means of two complementary observables.",
