Dynamic Decoherence Control of a Solid-State Nuclear-Quadrupole Qubit

Dynamic Decoherence Control of a Solid-State Nuclear-Quadrupole Qubit

We report on the application of a dynamic decoherence control pulse sequence on a nuclear-quadrupole transition in ${\mathrm{Pr}}^{3+}\ensuremath{\mathbin:}{\mathrm{Y}}_{2}{\mathrm{SiO}}_{5}$. Process tomography is used to analyze 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 …
