    "abstract": "We consider the problem of stabilizing the coherence of a single qubit\nsubject to Markovian decoherence, via the application of a control Hamiltonian,\nwithout any additional resources. In this case neither quantum error\ncorrection/avoidance, nor dynamical decoupling applies. We show that using\ntracking-control, i.e., the conditioning of the control field on the state of\nthe qubit, it is possible to maintain coherence for finite time durations,\nuntil the control field diverges.",
