The meanwhile 8. Quantum Tutorial by Dr. Holleczek enlightens the different QKD-Protocols, both, in reality and in simulation. Dr. Peter Holleczek Dates: 03.11.2025: Intro, BB84 10.11.2025: COW, COW-Stucki, COW-Walenta 17.11.2025: COW-Walenta Implementation 24.11.2025: BB84 Standalone si...

The small QKD satellite QUBE was recently able to establish a connection of the quantum modules to the ground station in order to demonstrate the use of tamper-proof QKD keys ...

The basic functionality of QKD has been demonstrated in the context of large (scientific) testbeds. International standards are also available. In the meantime, there are products that work in the normal operational/technical environment. Nevertheless, quantum key distribution (QKD) has so far its l...

In South Korea, a QKD cryptography system has now been officially certified for secure use for the first time.

Besides the mere generation of quantum-safe keys by Quantum Key Distribution (QKD), the further procedure with the keys, such as storage, management, and distribution to the target applications just in time, also plays a major role in the ongoing security. Often, this equally important field is stil...

In the field of quantum computers, another step towards commercialization could soon be achieved.

The Quantum Key Distribution (QKD) has limits, especially regarding distances. However, general useability has been shown in the context of large (scientific) testbeds. International standards are available. There already exist products that are suitable for normal operational/technical environments...
