This paper provides a comprehensive overview of the opportunities and challenges associated with the implementation of quantum communication technologies over optical satellite links. We explore the potential of such systems for long-distance quantum key distribution (QKD), quantum entanglement distribution, and the construction of global quantum networks that overcome the limitations of terrestrial fiber-based systems. The unique properties of optical satellite links, including their ability to span long distances with minimal signal loss, offer promising opportunities for robust quantum communications. However, there are significant technical and environmental challenges to realizing these systems, including atmospheric turbulence, beam tracking and pointing, and photon loss. In addition, we address the need for international cooperation, standardization and regulatory frameworks to ensure seamless integration into the existing communications infrastructure. By analyzing recent experimental demonstrations and theoretical developments, this paper highlights the crucial milestones that have been achieved and identifies key areas for future research. Our findings highlight the transformative potential of satellite-based quantum communications and its role in shaping the next generation of secure communication systems"},{"@xml:lang":"sl","#text":"Kvantna komunikacija prek optičnih satelitskih povezav je ključen korak h globalnim varnim komunikacijskim omrežjem. Ta članek ponuja celovit pregled priložnosti in izzivov povezanih z implementacijo kvantnih komunikacijskih tehnologij prek optičnih satelitskih povezav. Raziskujemo potencial sistemov za kvantno razdeljevanje ključev (angl. Quantum Key Distribution– QKD) na dolge razdalje, kvantno prepleteno razdeljevanje in izgradnjo globalnih kvantnih omrežij, ki presegajo omejitve zemeljskih sistemov temelječih na vlaknih. Edinstvene lastnosti optičnih satelitskih povezav, vključno z njihovo zmožnostjo pokrivanja velikih razdalj z minimalno izgubo signala, ponujajo obetavne priložnosti za robustne kvantne komunikacije. Vendar pa obstajajo pomembni tehnični in okoljski izzivi za uresničitev teh sistemov, ki se nanašajo na zračno turbulenco, sledenje in usmerjanje žarka ter izgubo fotonov. Poleg tega obravnavamo potrebo po mednarodnem sodelovanju, standardizaciji in regulativnih okvirih, da bi zagotovili brezhibno integracijo v obstoječo komunikacijsko infrastrukturo. Z analizo nedavnih poskusnih predstavitev in teoretičnega razvoja ta članek poudarja ključne mejnike, ki so bili doseženi, in opredeljuje področja za nadaljnji razvoj. ˇ Članek osvetljuje potencial satelitskih kvantnih komunikacij in njihovo vlogo pri oblikovanju naslednje generacije varnih komunikacijskih sistemov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-AJZPINO1","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-AJZPINO1"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-AJZPINO1/1b16fec9-f936-483a-8925-e1278ca5d46f/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Elektrotehniška zveza Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-AJZPINO1/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-AJZPINO1"}}}}
