    "abstract": "A generalization of the quantum XOR-gate is presented which operates in\narbitrary dimensional Hilbert spaces. Together with one-particle Fourier\ntransforms this gate is capable of performing a variety of tasks which are\nimportant for quantum information processing in arbitrary dimensional Hilbert\nspaces. Among these tasks are the preparation of Bell states, quantum\nteleportation and quantum state purification. A physical realization of this\ngeneralized XOR-gate is proposed which is based on non-linear optical elements.",
