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.","lang":"eng"}],"citation":{"bibtex":"@article{Elser_Bartley_Heim_Wittmann_Sych_Leuchs_2009, title={Feasibility of free space quantum key distribution with coherent polarization states}, number={4}, journal={New Journal of Physics}, author={Elser, D. and Bartley, Tim and Heim, B. and Wittmann, Ch and Sych, D. and Leuchs, G.}, year={2009}, pages={045014} }","ama":"Elser D, Bartley T, Heim B, Wittmann C, Sych D, Leuchs G.
