    "abstract": "Optimal labeling schemes lead to efficient experimental protocols for quantum\ninformation processing by nuclear magnetic resonance (NMR). A systematic\napproach of finding optimal labeling schemes for a given computation is\ndescribed here. The scheme is described for both quadrupolar systems and\nspin-1/2 systems. Finally, one of the optimal labeling scheme has been used to\nexperimentally implement a quantum full-adder in a 4-qubit system by NMR, using\nthe technique of transition selective pulses.",
