Course content
1. Classical cryptography, symmetrical and asymmetrical cryptosystems, mathematical complexity, quantum key distribution. Epsilon-security, authentication, quantum secret growing. 2. Discrete variables, non-cloning theorem, Bell inequalities. 3. Discrete-variable protocols: BB84, E91, modifications, information post-processing. 4. Classical information theory: discrete variables; Security analysis, QBER, individual/collective attacks. 5. Practical implementations: decoy-state, plug-and-play. 6. Practical issues: sources, channels, detectors, quantum hacking. 7. Continuous variables, Gaussian states, coherent-state protocol, squeezed-state protocol, entanglement-based implementation. 8. Classical information theory: continuous variables. Quantum capacity. Security analysis of continuous-variable protocols: individual/collective attacks, extremality of Gaussian states. 9. Practical issues: attenuation, noise, side-channels. 10. Realistic post-processing, finite-size effects. 11. Perspectives: secure quantum computing, quantum networking, repeaters, device-independent security.
