    "abstract": "We propose a generalization of quantum teleportation: the so-called\nmany-to-many quantum communication of the information of a d-level system from\nN spatially separated senders to M\u003eN receivers situated at different locations.\nWe extend the concept of asymmetric telecloning from qubits to d-dimensional\nsystems. We investigate the broadcasting of entanglement by using local 1-\u003e2\noptimal universal asymmetric Pauli machines and show that the maximal\nfidelities of the two final entangled states are obtained when symmetric\nmachines are applied. Cloning of entanglement is studied using a nonlocal\noptimal universal asymmetric cloning machine and we show that the symmetric\nmachine optimally copies the entanglement. The \"many-to-many\" teleportation\nscheme is applied in order to distribute entanglement shared between two\nobservers to two pairs of spatially separated observers.",
