  Symmetric informationally complete positive operator-valued measurement
(SIC-POVM) is one important class of quantum measurement which is crucial for
various quantum information processing tasks. SIC-POVMs have the advantage of
providing an unbiased estimator for quantum states with the minimal number of
outcomes needed for full tomography. We present an experimental approach on a
photonic quantum walk which can be used to implement SIC-POVMs on a
single-qbubit. The projection measurements of single-photons' positions
correspond to elements of SIC-POVM on the polarization of single-photons.
