Establishing secure communication links at a global scale is a major potential application of
quantum information science but also extremely challenging for the underlying technology …

Satellite internet serves as an indispensable component of the upcoming sixth‐generation
networks for providing global broadband internet access service. Due to the open nature of …

Geosynchronous Earth orbit (GEO) satellites can extend the transmission distance of the
quantum states and the intercrossing time between the satellites and the ground, which will …

Quantum key distribution (QKD) can provide unconditional security to next-generation
communication networks guaranteed by the laws of quantum physics. This article studies the …

In this work, we explore the feasibility of performing satellite-to-earth quantum key
distribution (QKD) using the orbital angular momentum (OAM) of light. Because of the …

The security of prepare-and-measure satellite-based quantum key distribution (QKD), under
restricted eavesdrop** scenarios, is addressed. We particularly consider cases where the …

Future quantum communication infrastructures will rely on both terrestrial and space-based
links integrating high-performance optical systems engineered for this purpose. In space …

In this study, a technique based on the quantum Fourier transform (QFT) that allows the
generation of disjoint sets of entangled particles is presented, in such a way that particles of …
