    "abstract": "We show how to construct a multi-qubit control gate on a quantum register of\nan arbitrary size N. This gate performs a single-qubit operation on a specific\nqubit conditioned by the state of other N-1 qubits. We provide an algorithm how\nto build up an array of networks consisting of single-qubit rotations and\nmulti-qubit control-NOT gates for the synthesis of an arbitrary entangled\nquantum state of N qubits. We illustrate the algorithm on a system of cold\ntrapped ions. This example illuminates the efficiency of the direct\nimplementation of the multi-qubit CNOT gate compared to its decomposition into\na network of two-qubit CNOT gates.",
