    "abstract": "A simple method is proposed to prepare conveniently the effective pure state\n|00...0\u003e\u003c0...00| with any number of qubits in a quantum ensemble. The\npreparation is based on the temporal averaging (Knill, Chuang, and Laflamme,\nPhys.Rev.A 57, 3348(1998)). The quantum circuit to prepare the effective pure\nstate is designed in a unified and systematical form and is explicitly\ndecomposed completely into a product of a series of one-qubit quantum gates and\nthe two-qubit diagonal quantum gates. The preparation could be programmed and\nimplemented conveniently on an NMR quantum computer.",
