Superadiabatic scheme for optimizing the fast generation of tree-type 3D entanglement

High-dimensional entanglement has more superior security than qubit entanglement. Recently, adiabatic and fast-adiabatic schemes for generating a novel three-dimensional (3D) entanglement, tree-type 3D entanglement, were proposed. However, the previous schemes have their experimental defects, respectively. Here we give a superadiabatic scheme for optimizing the generation of tree-type 3D entanglement. Adequate numerical simulations prove that the scheme is not only fast, effective and robust, but also highly feasible in experiment.
