    "abstract": "The ability to measure and reduce systematic errors in single-qubit logic\ngates is crucial when evaluating quantum computing implementations. We describe\npulsed electron paramagnetic resonance (EPR) sequences that can be used to\nmeasure precisely even small systematic errors in rotations of\nelectron-spin-based qubits. Using these sequences we obtain values for errors\nin rotation angle and axis for single-qubit rotations using a commercial EPR\nspectrometer. We conclude that errors in qubit operations by pulsed EPR are not\nlimiting factors in the implementation of electron-spin based quantum\ncomputers.",
