Content, Learning Outcome and Preconditions
Content
Photons travel with the speed of light and in various media can travel large distance without significant absorption. Therefore, they play a unique role in quantum technologies. The semiconductor platform is ideally suited for the generation of quantum states of light using quantum emitters and optically active spin qubits as well as for routing photons and creating effective photon-photon-interactions. This lecture will cover the fundamentals of semiconductor quantum photonics and their application in quantum technologies. Specific aspects are:
- Fundamentals of quantum photonics
- Examples of optically-active semiconductor qubits
- Quantum communication
- Photonic quantum computing
Learning Outcome
After successful completion of the module the students have developed a deep understanding of:
- Single qubits, two-qubit states and quantum entanglement
- Coherent light-matter interaction and resonator QED
- Advantages and disadvantages of different optically-active semiconductor qubits
- Different protocols for quantum communication and their implementation
- Possibilities to use photons for quantum computing
Preconditions
No preconditions in addition to the requirements for the Master’s program in Physics.
Courses, Learning and Teaching Methods and Literature
Learning and Teaching Methods
In the thematically structured lecture the learning content is presented. With cross references between different topics the universal concepts in semiconductor quantum photonics are shown. In scientific discussions the students are involved to stimulate their analytic-physics intellectual power.

Module Exam
Description of exams and course work
There will be a written exam of 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample problems.
For example an assignment in the exam might be:
- What is a quantum repeater and how does it work?
- What is a photonic cluster state and how can it be generated?
Exam Repetition
The exam may be repeated at the end of the semester.
