Quantum Communication

Module PH7005

This module is offered by Ludwig-Maximilians University Munich (LMU). It is available for TUM students only within a joint degree program (e. g. M. Sc. Quantum Science & Technology).

This module handbook serves to describe contents, learning outcome, methods and examination type as well as linking to current dates for courses and module examination in the respective sections.

Basic Information

PH7005 is a semester module in English language at Master’s level which is offered in winter semester.

This Module is included in the following catalogues within the study programs in physics.

  • Focus Area Experimental Quantum Science & Technology in M.Sc. Quantum Science & Technology

If not stated otherwise for export to a non-physics program the student workload is given in the following table.

Responsible coordinator of the module PH7005 is Harald Weinfurter.

Content, Learning Outcome and Preconditions


This module provides an introduction to quantum communication methods. Starting from quantum key distribution the module gives an overview of various methods like quantum teleportation and entanglement swapping, all the way to the design of efficient communication within a quantum network. The module introduces the basic theoretical concepts as well as the various tools and developments necessary to implement the new methods in real world scenarios.

Learning Outcome

After completing the Module the student is able to:

  1. Understand basic quantum communication methods and their relation to conventional communication systems.

  2. Understand the concepts of proofing the security and means to distill secure key of observed detection events.

  3. Understand entanglement based quantum communication methods.

  4. Understand basic quantum logic gate operations required, e.g., for entanglement purification and Bell state analysis.

  5. Understand the basic components in quantum communication implementations like laser diodes, generation of entangled photons, single photon detectors, coherent detection methods, quantum memories and systems suitable to implement quantum logic operations.

  6. Understand possible applications possible in quantum networks like distributed computation, efficient communication, scheduling, voting etc.


No prerequisites beyond the requirements for the Master’s program in Quantum Science and Technology.

Learning and Teaching Methods

The module consists of a lecture series (3 SWS) and exercise classes (1 SWS) per week. 

The main teaching material will be presented on the blackboard. This will be supplemented by power point / keynote / impress presentations to summarize / illustrate important results and discuss state-of-the-art research. Problem sets are offered to obtain a better comprehension of the lecture contents and to improve their familiarity with them. The exercise sessions are used to discuss the solutions to the problem sets and original publications related to the module.

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.


Power point, One Note, Impress presentation.


Special chapters in standard textbooks on quantum information, e.g.:

  • Lectures on Quantum Information, eds. D. Bruß, G. Leuchs, Wiley 2007. (als LMU-UB e-book)

  • The Physics of Quantum Information, eds. D. Bouwmeester, A. Ekert, A. Zeilinger, (Springer-Verlag Berlin) 2000.

  • Quantum Computation and Quantum Information, M. Nielsen, I. Chuang (Cambridge University Press) 2001. (als LMU-UB e-book)

Module Exam

Description of exams and course work

There will be a written exam of 120 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using conceptual questions and computational tasks.

For example an assignment in the exam might be:

  • Describe the protocol for quantum key distribution
  • Describe the principles and pros and cons of various single photon detectors
  • Show the polynomial scaling of the resources for the quantum repeater

Exam Repetition

The exam may be repeated at the end of the semester.

Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
