    "abstract": "Hadamard spectroscopy has earlier been used to speed-up multi-dimensional NMR\nexperiments. In this work we speed-up the two-dimensional quantum computing\nscheme, by using Hadamard spectroscopy in the indirect dimension, resulting in\na scheme which is faster and requires the Fourier transformation only in the\ndirect dimension. Two and three qubit quantum gates are implemented with an\nextra observer qubit. We also use one-dimensional Hadamard spectroscopy for\nbinary information storage by spatial encoding and implementation of a parallel\nsearch algorithm.",
