    "abstract": "While quantum information processing by nuclear magnetic resonance (NMR) with\nsmall number of qubits is well established, implementation of lengthy\ncomputations have proved to be difficult due to decoherence/relaxation. In such\ncircumstances, shallow circuits (circuits using parallel computation) may prove\nto be realistic. Parity and fanout gates are essential to create shallow\ncircuits. In this article we implement inversion-on-equality gate, followed by\nparity gate and fanout gate in 3-qubit systems by NMR, using evolution under\nindirect exchange coupling Hamiltonian.",
