    "abstract": "Quantum circuit network is a set of circuits that implements a certain\ncomputation task. Being at the center of the quantum circuit network, the\nmulti-qubit controlled phase shift is one of the most important quantum gates.\nIn this paper, we apply the method of modular structuring in classical computer\narchitecture to quantum computer and give a recursive realization of the\nmulti-qubit phase gate. This realization of the controlled phase shift gate is\nconvenient in realizing certain quantum algorithms. We have experimentally\nimplemented this modularized multi-qubit controlled phase gate in a three qubit\nnuclear magnetic resonance quantum system. The network is demonstrated\nexperimentally using line selective pulses in nuclear magnetic resonance\ntechnique. The procedure has the advantage of being simple and easy to\nimplement.",
