WebWe measure the coherence of a logic qubit stored in the hyperfine clock states of 43Ca+ while it is being actively cooled by a 40Ca+ refrigerator ion in the same trap. The 40Ca+ ion cools the 43Ca+ ion sympathetically, through the Coulomb interaction. We cool the stretch motion of the ion-pair using pulsed Raman sideband cooling.
