Ultracold neutral atoms are promising candidates for quantum information applications due to their long coherence times, scalability, and flexibility in encodings and connectivity. Strontium-87’s nuclear spin provides with a 10-dimensional nuclear spin manifold in its ground state, subspaces of which have been leveraged to realize a qubit. We report on our ongoing experimental efforts to implement a Strontium-based quantum computing architecture, based on quantum control and entanglement of large d-dimensional (up to d=10) nuclear spin qudits. Our work targets mid-circuit quantum non-demolition (QND) erasure detection and QND cooling of qudits, as well as single- and two-qudit gates based on quantum control.
