Pushing the Frontiers: Artificial Intelligence (AI)‐Guided Programmable Concepts in Binary Self‐Assembly of Colloidal Nanoparticles

Advanced Science, Volume 12, Issue 28, July 24, 2025.
Colloidal nanoparticles self‐assembly advances towards intelligent, customized assembly through precise control of binary co‐assemblies. This review explores the evolution from monolithic to binary assemblies, highlighting how the AI‐guided programmable assembly approach has the potential to shift from passive assembly to active intelligent design.

Ultralow Photon Flux OWC Links Using UV‐C Single‐Photon Detection

Laser &Photonics Reviews, Volume 19, Issue 13, July 8, 2025.
This work presents ultralow photon flux UV‐C optical wireless communication (OWC) links using a micro‐LED and a silicon photomultiplier (SiPM)‐based single‐photon detector (SPD). A record‐low transmission of 7.7 photons per bit and a maximum data rate of 120 Mbit s−1 are achieved. Furthermore, single‐photon links highlight the potential for a future UV‐

Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons

Advanced Quantum Technologies, Volume 8, Issue 7, July 2025.
Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...
