QUANTUM INFORMATION WITH OPTICAL CONTINUOUS VARIABLES: Nonlocality, Entanglement, and Error Correction

ii Acknowledgments My gratitude goes to Nicolas Cerf for introducing me to the fascinating field of quantum information, and for giving me the opportunity to pursue this thesis. I would also like to thank all of my colleagues at the QuIC, in particular Lo¨ıck Magnin who read a preliminary version of this manuscript, and Louis-Philippe Lamoureux who has become a true friend. Some of the results of this dissertation come from fruitful collaborations. I am very grateful to Antonio Acín and his group at the Institute of Pho-tonic Sciences of Barcelona. My two visits at the ICFO provided me with both inspiration and Sun. I am also grateful to Ulrik L. Andersen of the Technical University of Denmark for his great expertise in quantum optics and outstanding experimental skills. Finally, I would like to thank Jaromir Fiurášek of the University of Palack´y for always finding time to answer my questions. To my friends, to my family, to Veronika.
