Cryogenic Strontium Quantum Processor — •Roberto Franco, Xintong Su, Valerio Amico, Jonas Drotleff, and Christian Gross — University of Tübingen

In our project we aim at the unification of the optical tweezer technology with cryogenic technology at 4K, exploiting the stability of nuclear spin qubits encoded in fermionic strontium. This will result in record-long coherence and lifetimes of the atoms in the optical tweezer array. We report our efforts on the architecture to perform single qubit gates and the plans for adding two-qubit gates in the experiment.
