Quantum cryptography harnesses quantum light, in particular single photons, to provide security guarantees that cannot be reached by classical means. For each cryptographic task, the security feature of interest is… Weiter »Enhancing quantum cryptography with quantum dot single-photon sources

Numerical optimization of single-mode fiber-coupled single-photon sources based on semiconductor quantum dots

  • Lucas Bremer, Carlos Jimenez, Simon Thiele, Ksenia Weber, Tobias Huber, Sven Rodt, Alois Herkommer, Sven Burger, Sven Höfling, Harald Giessen, Stephan Reitzenstein

We perform extended numerical studies to maximize the overall photon coupling efficiency of fiber-coupled quantum dot single-photon sources emitting in the near-infrared and telecom regime. Using the finite element method,… Weiter »Numerical optimization of single-mode fiber-coupled single-photon sources based on semiconductor quantum dots
