    "abstract": "We present some dynamic and entropic considerations about the evolution of a\ncontinuous time quantum walk implementing the clock of an autonomous machine.\nOn a simple model, we study in quite explicit terms the Lindblad evolution of\nthe clocked subsystem, relating the evolution of its entropy to the spreading\nof the wave packet of the clock. We explore possible ways of reducing the\ngeneration of entropy in the clocked subsystem, as it amounts to a deficit in\nthe probability of finding the target state of the computation. We are thus\nlead to examine the benefits of abandoning some classical prejudice about how a\nclocking mechanism should operate.",
