The physical description of all materials is rooted in quantum mechanics, which describes
how atoms bond and electrons interact at a fundamental level. Although these quantum …

Quantum key distribution (QKD) is a family of protocols for growing a private encryption key
between two parties. Despite much progress, all ground-based QKD approaches have a …

Driven by the rapid escalation of the wireless capacity requirements imposed by advanced
multimedia applications (eg, ultrahigh-definition video, virtual reality, etc.), as well as the …

Vector vortex beams are structured states of light that are nonseparable in their polarisation
and spatial mode, they are eigenmodes of free-space and many fiber systems, and have the …

We report on entanglement-based quantum key distribution between a low-Earth-orbit
satellite equipped with a space borne entangled-photon source and a ground observatory …

To fully unleash the potentials of quantum computing, several new challenges and open
problems need to be addressed. From a routing perspective, the optimal routing problem, ie …

Processing of digital images is continuously gaining in volume and relevance, with
concomitant demands on data storage, transmission, and processing power. Encoding the …

Satellite-based quantum terminals are a feasible way to extend the reach of quantum
communication protocols such as quantum key distribution (QKD) to the global scale. To that …

Quantum technology establishes a foundation for secure communication via quantum key
distribution (QKD). In the last two decades, the rapid development of QKD makes a global …
