    • Note that classical random walks can be easily obtained by removing all the phase shifters. In this case, indeed, there can be no destructive interference that makes the quantum random walk different from its classical counterpart.

    • note
    • More precisely, while the number of beam splitters grows as N, the required AOMs and phase shifters increases as 2N. However, in the spirit of the proposal shown in Fig. 1, we can consider basic building blocks made by a beam splitter, two phase shifters, and two AOMs (as the one boxed in Fig. 3). This clarifies that, in this case, the number of building blocks grows linearly with N.
