Abstract

This paper reports the realization of a quantum network node using a trapped ion inside a fiber-based Fabry-Perot cavity. Deterministic entanglement between a trapped Yb ion and a photon emitted into the resonator mode is achieved with a high fidelity of 90.1(17)%. The success probability for entanglement generation and detection is 2.5 × 10⁻³, resulting in a 62 Hz entanglement rate.
