Abstract
A simple and flexible scheme for high-dimensional linear quantum operations is demonstrated on optical discrete spatial modes in the transverse plane. The quantum state tomography (QST) via symmetric informationally complete positive operator-valued measures (SIC POVMs) and quantum Fourier transformation (QFT) are implemented with dimensionality of 15. The statistical fidelity of SIC POVMs and fidelity of QST are $$0.97 and up to 0.853, respectively, while the matrix fidelity of QFT is 0.85. We believe that our approach has the potential for further exploration of high-dimensional spatial entanglement provided by spontaneous parametric down conversion in nonlinear crystals.
