Since repeating in quantum networks is not ready for operation anytime soon, a more modest approach is needed for network construction. The remedy is smaller-scale and more tightly meshed networks in the 100km range. This places higher demands on security and performance, especially for key generati...

The two application areas "Time&Frequency" (T&F) and quantum communication (QuC) have special technical requirements for data networks. For the transfer of high-quality signals, T&F requires bi-directional amplification, which in conventional data networks requires the signals to be d...

Deepening Repeater: "Quantum repeating" is a core element of a functioning transmission of information over a larger distance. Due to the no-cloning theorem, creating a quantum duplicate, as is common in classical signal processing, is not possible. Therefore, it requires new network devices such as...

We have extended our Quantum Simulation portal. You will now find documents in which we describe our impressions of various quantum simulators that we have installed and tried (german language) out. Also a catalog (german language) with simulators that we think are interesting.

In the future, articles with tutorial character will be published in this new section. It can be found in the Quantum Technologies portal alongside other sections such as Fundamentals, Quantum Computing, Quantum Initiatives, Quantum Networks, Quantum Simulation and Further Information.

Quantum simulators in practice Quantum simulators in practice in DFN-Mitteilungen 101 page 38 If you want to get a closer look at quantum computing right now, you can use simulators to get a good start in the world of QuBits, quantum networks and tap-proof quantum protocols. The article offers p...

Twice a year, the German Research Network Association publishes the DFN-Mitteilungen on interesting topics related to research infrastructure, security and state-of-the-art information. This time there is again a contribution from the WiN-Lab, in which we present quantum simulators and show how alg...

The history of the development of data communications has actually been told. Progress is currently limited to a slight increase in transmission rates. Progress is hampered technically by ever more arduous miniaturization and organizationally by ever more stringent security requirements. Leap innova...

Quantum Networks - Between Reality and Future Quantum Networks - Between Reality and Future in DFN-Mitteilungen 100 page 34 They have long since ceased to be mere dreams of the future, but are mostly in an experimental state - quantum networks. Our author Dr. Peter Kaufmann and our author Dr. Su...
