    "abstract": "Within a special multi-coin quantum walk scheme we analyze the effect of the\nentanglement of the initial coin state. For states with a special entanglement\nstructure it is shown that this entanglement can be meausured with the mean\nvalue of the walk, which depends on the i-concurrence of the initial coin\nstate. Further on the entanglement evolution is investigated and it is shown\nthat the symmetry of the probability distribution is reflected by the symmetry\nof the entanglement distribution.",
