Getting acquinted with quantum description of light and most important quantum effects in optics.

Knowledge and understanding:

Knowledge of basic concepts and methods of quantum optics, understandong the difference between quantum and classical interpretation of light.

Application:

Acquired knowledge is the basis for a detailed discussion of laser physics and quantum informatics.

Reflection:

Deepened understanding of quantum effects nature, light as an aexmaple of quantified field.

Transferable skills:

Usage of stohastic techniques and discussion of operator equations.

Lectures, numerical exercises, homework, seminars, consultations.

Final written exam or exams from exercises during the course

Oral exam

grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
