Abstract ： Multi-dimensional entangled states have been proven to be more powerful in some quantum information processes. Down-converted photons from spontaneous parametric down-conversion are used to engineer multi-dimensional entangled states. A kind of multi-degree multi-dimensional Greenberger--Horne--Zeilinger states can also be generated. The hyper-entangled photons are entangled in energy-time, polarization and orbital angular momentum, which is proven to be useful to increase the dimension of systems and to investigate higher-dimensional entangled states.
