    "abstract": "Quantum robots and their interactions with environments of quantum systems\nare described and their study justified. A quantum robot is a mobile quantum\nsystem that includes a quantum computer and needed ancillary systems on board.\nQuantum robots carry out tasks whose goals include specified changes in the\nstate of the environment or carrying out measurements on the environment. Each\ntask is a sequence of alternating computation and action phases. Computation\nphase activities include determination of the action to be carried out in the\nnext phase and possible recording of information on neighborhood environmental\nsystem states. Action phase activities include motion of the quantum robot and\nchanges of neighborhood environment system states. Models of quantum robots and\ntheir interactions with environments are described using discrete space and\ntime. To each task is associated a unitary step operator T that gives the\nsingle time step dynamics. T = T_{a}+T_{c} is a sum of action phase and\ncomputation phase step operators. Conditions that T_{a} and T_{c} should\nsatisfy are given along with a description of the evolution as a sum over paths\nof completed phase input and output states. A simple example of a task carrying\nout a measurement on a very simple environment is analyzed. A decision tree for\nthe task is presented and discussed in terms of sums over phase paths. One sees\nthat no definite times or durations are associated with the phase steps in the\ntree and that the tree describes the successive phase steps in each path in the\nsum.",
