Multi-Species Trapped Ion Node for Quantum Networking

Abstract

Trapped atomic ions are a leading platform for quantum information networks, with long-lived identical qubit memories that can be locally entangled through their Coulomb interaction and remotely entangled through photonic channels. However, performing both local and remote operations in a single node of a quantum network requires extreme isolation between spectator qubit memories and qubits associated with the photonic interface. We achieve this isolation and demonstrate the ingredients of a scalable ion trap network node by co-trapping ${}^{171}$Yb${}^{+}$ and ${}^{138}$Ba${}^{+}$ qubits, entangling the mixed species qubit pair through their collective motion, and entangling the ${}^{138}$Ba${}^{+}$ qubits with emitted visible photons.
