Trapped atomic ions are among the most attractive implementations of quantum bits for applications in quantum information processing, owing to their long trapping lifetimes and long coherence times. While nearby trapped ions can be entangled through their Coulomb-coupled motion, networking remotely-located ions requires a photonic coupling. When two atomic ions each become entangled with an emitted single photon, subsequent interference and detection of these photons can leave the trapped ion qubits in an entangled state. Although this entanglement is probabilistic, it is not post-selective and therefore can be utilized for long-distance quantum communication and large-scale quantum computation.
