    Research output: Contribution to journalArticlepeer-review


    The effects of certain forms of decoherence applied to adiabatic and nonadiabatic geometric phase quantum gates were studied. Effects of isotropic noise were set by the gate length and level of decoherence. Results indicated that the anisotropic noise-sensitive gates coupled with the ability to reorienate the external static magnetic field, could be applied in mapping out the forms of decoherence acting on a qubit. The single-qubit decoherence calibrations could be used to predict the expected level of entanglement in two-qubit gates prior to experiment.
