Interfacing a single trapped ion qubit with a single photon flying quibit

We report a series of experiments linking an ideal quantum memory with an ideal quantum communication channel. A single trapped ion probabalistically emits a single photon in such a way that the internal state of the trapped ion is entangled with the polarization of the photon. The entanglement is directly verified via measurements of correlations and Bell inequality violations. While the process is probabalistic, it can nevertheless be scaled to large numbers of qubits following known quantum repeater protocols.
