    "abstract": "We propose the scheme implementing partial deterministic non-demolition Bell\nmeasurement. When it is used in quantum teleportation the information about an\nunknown input state is optimally distributed among three outgoing qubits. The\noptimality means that the output fidelities saturate the asymmetric cloning\ninequality. The flow of information among the qubits is controlled by the\npreparation of a pair of ancillary qubits used in the Bell measurement. It is\nalso demonstrated that the measurement is optimal two-qubit operation in the\nsense of the trade-off between the state disturbance and the information gain.",
