A commercial quantum key distribution (QKD) system needs to be formally certified to
enable its wide deployment. The certification should include the system's robustness against …

In quantum communication systems, the precise estimation of the detectors response to the
incoming light is necessary to avoid security breaches. The typical working regime uses a …

Room temperature quantum emitters have been reported in aluminum nitride grown on
sapphire, but until now they have not been observed in epilayers grown on silicon. We …

Single-photon sources with photon antibunching characteristics are essential for quantum
information technologies. This paper investigates the potential of quaternary-alloy CdTeSeS …

We can get a clearer picture of the microcosm around us by studying individual molecules.
Since a molecule is only a few angstroms (10⁻ ¹⁰ m) in size, we can not observe or study …

Abstract Quantum Key Distribution (QKD) theoretically provides information-theoretic
security based on physical laws. However, imperfections in practice lead to the possibility of …

Quantum technologies are driving more and more interest both in academia and industry
thanks to their promising performances in terms of security. In reality, practical systems suffer …

Abstract Quantum Key Distribution (QKD) performs key establishment by employing
quantum physics to guarantee communication security. This technology has received much …
