    "abstract": "We discuss the implementation of frequency selective rotations using\nsequences of hard pulses and delays. These rotations are suitable for\nimplementing single qubit gates in Nuclear Magnetic Resonance (NMR) quantum\ncomputers, but can also be used in other related implementations of quantum\ncomputing. We also derive methods for implementing hard pulses in the presence\nof moderate off-resonance effects, and describe a simple procedure for\nimplementing a hard 180 degree rotation in a two spin system. Finally we show\nhow these two approaches can be combined to produce more accurate frequency\nselective rotations.",
