Monolithic cointegration of QD-based InP on SiN as a versatile platform for the demonstration of high performance and low cost PIC transmitters (MOICANA)


28.02.2016 - 16:54 article in the „Physik in unserer Zeit“

A recent open-access article by research partners from the BMBF Research Network project entitled "Sichere Kommunikation per Quantenrepeater" is published in "Physik in unserer Zeit", which reports on the current state and the main challenges in this field.


Project QuaHL-Rep

This project is a national cooperative project supported by the German Ministry of Eduction and Research (BMBF) and is entitled "Quanten-Repeater Plattformen auf der Basis von Halbleitern" (QuaHL-Rep). The overall objective of the project is the development of material platforms that are suitable for the realization of the quantum repeater protocols to transmit secure quantum information over large distances. To fulfill the tasks of the QuaHL-Rep, thirteen groups were brought together to work on different approaches.
