Coherent Control of the Fine-Structure Qubit in a Single Alkaline-Earth Atom

Govind Unnikrishnan, Philipp Ilzhöfer, Achim Scholz +10

We report on the first realization of a novel neutral atom qubit encoded in the metastable fine-structure states ${}^3{\mathrm{P}}_0$ and ${}^3{\mathrm{P}}_2$ of single ${}^{88}$Sr atoms trapped…
