Quantum photonic communication

• Describe the concept and the advantages of a quantum information network, including several modern implementation approaches.
• Explain coherence and decoherence in quantum systems, including semiconductor based two-level systems.
• Describe & Operate single-photon sources and single-photon detectors.
• Explain the main quantum communication protocols, including discrete variable and continuous variable systems with a focus on multidimensional quantum systems.
• Identify & Describe the major challenges in field, including quantum hacking and long distance communication with quantum repeaters.
• Use state-of-the-art equipment and techniques for quantum photonics experiments, including single-photon correlation measurements, two-photon interference and quantum key distribution.
• Analyze experimental data and draw conclusions.
• Evaluate critically the presented topics from a scientific point of view.

The course will be composed of:

— Lectures on the state-of-the-art in optical communication, introduction to quantum optics and quantum networks, quantum state transfer, quantum coherence, and decoherence, single-photon sources and detectors, quantum cryptography, and quantum error correction.

— Student seminars on the topic, for instance, on specific quantum communication protocols. The actual subjects will be discussed and defined together with the students during the course.

— Laboratory experiments on fundamentals of quantum physics, which until recently could only be done in research labs.
