• Abstract summary: We demonstrate the conversion of single photons emitted from a III-V semiconductor quantum dot at 853nm via sum frequency conversion to the wavelength of the strong transition of Yb ions at 370nm. We show that the single-photon character of the quantum dot emission is preserved during the conversion process.

• Abstract: Wavelength conversion at the single-photon level is required to forge a quantum network from distinct quantum devices. Such devices include solid-state emitters of single or entangled photons, as well as network nodes based on atoms or ions. Here we demonstrate the conversion of single photons emitted from a III-V semiconductor quantum dot at 853nm via sum frequency conversion to the wavelength of the strong transition of Yb ions at 370nm. We measure the second-order correlation function of both the unconverted and of the converted photon and show that the single-photon character of the quantum dot emission is preserved during the conversion process.

  Trapped ions are one of the leading candidates for scalable and long-distance quantum networks. One method for creating ion-photon entanglement is to exploit optically transitions from the P_(1/2) to S_(1/2) levels. We use a two-stage quantum frequency conversion scheme to achieve a frequency shift of 375.4 THz between the input visible photon and the output telecom photon.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
