{"abstract":[{"lang":"eng","text":"We demonstrate for the first time the feasibility of free space quantum key distribution with continuous variables under real atmospheric conditions. More specifically, we transmit coherent polarization states over a 100 m free space channel on the roof of our institute's building. In our scheme, signal and local oscillator (LO) are combined in a single spatial mode, which auto-compensates atmospheric fluctuations and results in an excellent interference. Furthermore, the LO acts as a spatial and spectral filter, thus allowing unrestrained daylight operation."}],"type":"journal_article","publication":"New Journal of Physics","department":[{"_id":"15"}],"user_id":"49683","date_created":"2018-06-06T12:34:08Z","status":"public","issue":"4","language":[{"iso":"eng"}],"title":"Feasibility of free space quantum key distribution with coherent polarization states","publication_identifier":{"issn":["1367-2630"]},"year":"2009","date_updated":"2022-10-11T07:22:40Z","page":"045014","extern":"1","author":[{"full_name":"Elser, D.","last_name":"Elser","first_name":"D."},{"first_name":"Tim","last_name":"Bartley","id":"49683","full_name":"Bartley, Tim"},{"last_name":"Heim","first_name":"B.","full_name":"Heim, B."},{"first_name":"Ch","last_name":"Wittmann","full_name":"Wittmann, Ch"},{"last_name":"Sych","first_name":"D.","full_name":"Sych, D."},{"full_name":"Leuchs, G.","first_name":"G.","last_name":"Leuchs"}],"citation":{"ama":"Elser D, Bartley T, Heim B, Wittmann C, Sych D, Leuchs G.
