For some time now, research into Photonic Integrated Circuits (PICs) has been considered a breakthrough in QKD technology, that is expected to be produced in large quantities. In addition, the small pluggables with optical circuits are much more practical than a 19" box. Also high speeds and energy ...

In China, there is now an even larger carrier-grade quantum network over 10103 km, both with wired quantum connections and over free space routes with six ground stations. The currently largest QKD network in the world consists of ...

After the American company Qubitekk (leading in quantum networks) was acquired at the turn of the year, the Swiss company ID Quantique (IDQ) now also counts as an IonQ's subsidiary https://ionq.com/. IDQ is one of the few globally established manufacturers of QKD-devices in the EU-related environ...

14 PQC algorithms advance to the second round of NISTs Post-Quantum Digital Signatures Standardization Process

After 8 years of research on the methods, the first three quantum-secure PQC algorithms have now been standardized by NIST: FIPS 203, Module-Lattice-Based Key-Encapsulation Mechanism Standard (ML-KEM) based on Crystals-Kyber FIPS 204, Module-...

Since the beginning of the year, a growing number of countries have enacted explicit export controls for quantum computers and associated technology in the context of the dual-use issue. The presence of identical wording suggests secret preliminary negotiations. In Germany, according to an official ...

A collaboration of researches from the Imperial College London, the University of Stuttgart, the Julius Maximilian University of Würzburg and the University of Southampton succeeded in demonstrating writing to and reading from a quantum memory. The used photons were created in a single-photon source...
