Recently, a dual-type qubit scheme has been realized in a quantum network node where communication qubits and memory qubits are encoded in different energy levels of the same ion species, such that the generation of ion-photon entanglement on the communication qubits has negligible cross-talk error on the preloaded quantum information in the memory qubits. However, to achieve versatile applications of a quantum network, a crucial component of the dual-type node, namely, the entangling gate between the communication and the memory qubits, is still missing. Here, we report a dual-type quantum network node equipped with ion-photon entanglement generation, cross-talk\u2013free quantum memory, and entangling gates between dual-type qubits simultaneously. We demonstrate its practical applications including the passive quantum-state teleportation and the preparation of multipartite entangled state. Our work achieves the necessary components of a dual-type quantum network node.<\/jats:p>","DOI":"10.1126\/sciadv.aeb4076","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T18:59:02Z","timestamp":1764788342000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":1,"title":["Realization
