The realization of a multinode quantum network is the first necessary step towards the implementation of the quantum internet. With this target in mind, we will report on a recent experiment where successful full-photonic quantum teleportation has been achieved, employing two remote quantum dots as sources of quantum light. This experiment exploited quantum frequency conversion to enable operation at telecom wavelength. [1] The successful teleportation achieved with two distinct sources lay the foundation to future experiments: it shows scalability of this approach, compatibility with fibre networks, interoperability of different systems (as semiconductor quantum dots and frequency conversion elements), and operation of distinct nodes. All are necessary steps towards the implementation of a realistic quantum network.
