    "abstract": "Quantum computing using two-dimensional NMR has recently been described using\nscalar coupling evolution technique [J. Chem. Phys.,109,10603 (1998)]. In the\npresent paper, we describe two-dimensional NMR quantum computing with the help\nof selective pulses. A number of logic gates are implemented using two and\nthree qubits with one extra observer spin. Some many-in-one gates (or\nPortmanteau gates) are implemented. Toffoli gate (or AND/NAND gate) and OR/NOR\ngates are implemented on three qubits. Deutsch-Jozsa quantum algorithm for one\nand two qubits, using one extra work qubit, has also been implemented using\nselective pulses after creating a coherent superposition state, in the\ntwo-dimensional methodology.",
