Resumen
La búsqueda de manifestaciones cuánticas coherentes a escala macroscópica es actualmente intensa. En especial, con la fabricación de nanoestructuras semiconductoras se ha podido llegar a un nivel de control tanto espacial como temporal donde esos efectos cuánticos asombrosos pudieran ser demostrados. En este artículo se presenta una revisión crítica de resultados recientes sobre la creación de estados cuánticos enredados en sistemas de puntos cuánticos, la observación de su decoherencia en escalas de tiempo del orden de picosegundos, así como también la transferencia de coherencias entre un estado cuántico macroscópico tipo condensado de Bose-Einstein y la luz que emite.
