Communications Quantiques

Quantum Communications

Description: This course provides a structured and in-depth introduction to quantum communications, a core area of quantum technologies grounded in the principles of quantum mechanics and information theory. The course introduces the foundations of quantum information, including qubits, entanglement, quantum measurements, and noisy quantum channels, as well as the fundamental limits imposed by quantum laws on information transmission. Particular emphasis is placed on the analysis of performance, losses, and noise in realistic communication scenarios.

The course then covers the main quantum communication protocols, such as quantum key distribution (QKD), quantum teleportation, and superdense coding, together with issues of information-theoretic security and quantum error correction. Long-distance communication challenges are addressed through the study of quantum repeaters and emerging quantum network architectures. Problem-solving sessions complement the lectures, allowing students to apply theoretical concepts to analytical and numerical case studies inspired by real-world systems. By the end of the course, students will have acquired the conceptual tools required to understand, model, and assess modern quantum communication systems and their role in the development of a future quantum Internet.
