Dynamic decoherence control of a solid-state nuclear quadrupole qubit
E. Fraval, M. J. Sellars, J. J. Longdell
abstract: We report on the application of a dynamic decoherence control pulse sequence
on a nuclear quadrupole transition in $Pr^{3+}:Y_2SiO_5$ . Process tomography
is used to analyse the effect of the pulse sequence. The pulse sequence was
found to increase the decoherence time of the transition to over 30 seconds.
Although the decoherence time was significantly increased, the population terms
were found to rapidly decay on the application of the pulse sequence. The
increase of this decay rate is attributed to inhomogeneity in the ensemble.
Methods to circumvent this limit are discussed.
