    "abstract": "The controlled-NOT gate and controlled square-root NOT gate play an important\nrole in quantum algorithm. This article reports the experimental results of\nthese two universal quantum logic gates (controlled square-root NOT gate and\ncontrolled-NOT gate) on a 7-qubit NMR quantum computer. Further, we propose a\nsimple experimental method to measure and correct the error in the controlled\nphase-shift gate, which is helpful to construct a more perfect phase-shift gate\nexperimentally and can also be used in more qubits discrete Fourier\ntransformation.",
