dc.description.abstractWe prepare a source of 4-dimensional photon states entangled in the polarization and energy-time degrees of freedom. The photon pairs are generated via spontaneous parametric down-conversion process. This hyperentanglement can be used for various quantum communication protocols and fundamental tests of quantum physics. It is possible to determine the presence of entanglement in higher dimensions by appealing to a dimension witness like the Collins-Gisin-Linden-Massar-Popescu (CGLMP) ineqaulity. From the correlations measurement between the entangled photons, we perform a dimension witness measurement to deduce the lower bound of the dimensionality of the system without any theoretical assumptions and find that our system has at least a dimensionality of 3. However, the CGLMP bound for 4-dimension is not violated due to the stability issues in our interferometric setup.
