Quantum information with optical continuous variables: from Bell tests to key distribution

Quantum information with optical continuous variables: from Bell tests to key distribution

In this thesis we have studied different aspects of the novel field of quantum information with continuous variables. The higher efficiency and bandwidth of homodyne detection combined with the easiness of generation and manipulation of Gaussian states makes continuous-variable quantum information a...
