    "abstract": "Composite pulse sequences designed for nuclear magnetic resonance experiments\nare currently being applied in many quantum information processing\ntechnologies.We present an analysis of a family of composite pulse sequences\nused to address systematic pulse-length errors in the execution of quantum\ngates. It has been demonstrated by Cummins et al. [Phys. Rev. A 67, 042308\n(2003)] that for this family of composite pulse sequences, the fidelity of the\nresulting unitary operation compared with the ideal unitary operation is\n1+C*epsilon^6, where epsilon is the fractional error in the length of the\npulse. We derive an exact expression for the 6th order coefficient, C, and from\nthis deduce conditions under which this 6th order dependance is observed. We\nalso present new pulse sequences which achieve the same fidelity.",
