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."}],"author":[{"last_name":"Elser","full_name":"Elser, D.","first_name":"D."},{"id":"49683","last_name":"Bartley","full_name":"Bartley, Tim","first_name":"Tim"},{"first_name":"B.","last_name":"Heim","full_name":"Heim, B."},{"first_name":"Ch","last_name":"Wittmann","full_name":"Wittmann, Ch"},{"first_name":"D.","last_name":"Sych","full_name":"Sych, D."},{"first_name":"G.","full_name":"Leuchs, G.","last_name":"Leuchs"}],"extern":"1"}
