    "abstract": "We address the problem of implementing high fidelity one-qubit operations\nsubject to time dependent noise in the qubit energy splitting. We show with\nexplicit numerical results that high fidelity bit flips and one-qubit NOT gates\nmay be generated by imposing bounded control fields. For noise correlation\ntimes shorter than the time for a pi-pulse, the time optimal pi-pulse yields\nthe highest fidelity. For very long correlation times, fidelity loss is\napproximately due to systematic error, which is efficiently tackled by\ncompensation for off-resonance with a pulse sequence (CORPSE). For intermediate\nranges of the noise correlation time we find that short CORPSE, which is less\naccurate than CORPSE in correcting systematic errors, yields higher fidelities.\nNumerical optimization of the pulse sequences using gradient ascent pulse\nengineering results in noticeable improvement of the fidelities for the bit\nflip and marginal improvement for the NOT gate.",
