Entanglement measurement with discrete multiple coin quantum walks — •Jochen Endrejat and Helmut Buettner — Theoretische Physik I, Universitaet Bayreuth
Within a special multi-coin quantum walk scheme we analyze the effect of the entanglement of the initial coin state. For states with a special entanglement structure it is shown that this entanglement can be meausured with the mean value of the walk, which depends on the i-concurrence of the initial coin state.
