El adecuado diseño de los elementos que recolectan la luz en el receptor es crítico para un buen desempeño. Así, el objetivo principal del presente trabajo es presentar una metodología de diseño de antenas ópticas empleadas en comunicación cuántica. Se muestra la factibilidad y utilidad de la teoría paraxial para este diseño, permitiendo el empleo de componentes ópticos, tales como telescopios astronómicos usados en esquemas clásicos convencionales. Con la ayuda de herramientas de simulación, diseñamos una antena óptica para 1550 nm, empleando un telescopio tipo Cassegrain, y realizamos una prueba de concepto en laboratorio siendo capaces de captar tres fotones por bit validando la metodología sugerida.]]></p></abstract>

Proper design of the elements that collect light in the receiver is critical for good performance. So, the main objective of this paper is to present an optical antennas design methodology used in quantum communications. This article shows feasibility and utility of paraxial theory use for this design which allows the use of optical components such as astronomical telescopes used in conventional classical schemes. An optical antenna for 1550 nm was designed with the help of simulation tools and a commercial Cassegrain type telescope. Also, a proof of concept in the laboratory was performed where three photons per bit were captured, validating as well the suggested methodology.]]></p></abstract>
