Efficient fibre-based long-distance quantum communication via quantum repeaters relies on
deterministic single-photon sources at telecom wavelengths, potentially exploiting the …

In this paper, the design of superconducting-nanowire single-photon detectors which are
insensitive to the polarization of the incident light is investigated. By using high-refractive …

We designed a low-filling-factor and polarization-sensitive superconducting nanowire single
photon detector (SNSPD), which can achieve a high absorption efficiency and counting rate …

The scope of this thesis is the development of efficient and low-background polarization-
preserving quantum frequency converters (PPQFC) and their integration into trapped-atom …

Future quantum networks require a hybrid platform of dissimilar quantum systems. Within the
platform, joint quantum states have to be mediated either by single photons, photon pairs or …
