Self-stabilized high-dimensional quantum key distribution on a metropolitan free-space link
Karolina Dziwulska, Christopher Spiess, Sarika Mishra +3
Quantum communication technologies capable of operating reliably across heterogeneous optical channels are essential for scalable metropolitan quantum networks. Here we demonstrate…
Asynchronous Multi-photon Interference for Quantum Networks
Baghdasar Baghdasaryan, Karen Lozano-Méndez, Markus Leipe +11
Advanced quantum communication protocols require high-visibility quantum interference between photons generated at distant nodes, which places stringent demands on optical synchron…
A plug-and-play solution for characterizing two-way optical frequency transfer over free-space
Jingxian Ji, Shambo Mukherjee, Alexander Kuhl +5
Optical clock networks connected by phase-coherent links offer significant potential for advancing fundamental research and diverse scientific applications. Free-space optical freq…
Ad-hoc hybrid-heterogeneous metropolitan-range quantum key distribution network
Matthias Goy, Jan Krause, Ãmer Bayraktar +37
This paper presents the development and implementation of a versatile ad-hoc metropolitan-range Quantum Key Distribution (QKD) network. The approach presented integrates various ty…
