Quantum photonic communication

Overall Course Objectives

Watch our video:

Quantum photonics is now ready to be transferred from research labs to innovative and useful technologies. This course is set up to address this challenge and has three main objectives:

1. To prepare the student for the technology of tomorrow in information transfer — the Quantum Internet.

2. To equip the student with basic and advanced knowledge about this technological platform:
— Fundamentals of quantum information transfer
— Quantum communication protocols — from the most promising solutions to the latest inventions
— Major challenges in the field

3. To give the student hands-on experience with the key experiments that reveal the nature of quantum physics:
— Quantum light source
— Two-photon interference
— Quantum entanglement

Learning Objectives

  • 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.

Course Content

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.
