The result of studying the course "Quantum Optics" is an understanding of the principles of describing the free electromagnetic field using sequential quantum theory; ability to use the basic apparatus of quantum electrodynamics to analyze the processes of interaction of the electromagnetic field with matter; ability to determine the main characteristics of the quantum state of the field of electromagnetic radiation; the ability to evaluate the highest achievable accuracy in a particular optical experiment.

Full-time form

The student must have knowledge of: nonrelativistic quantum mechanics, classical optics, basics of measuring the characteristics of optical fields. The student must be able to: use the methods of classical electrodynamics, wave optics and nonrelativistic quantum mechanics.

Lectures, practical classes

Assessment of knowledge is carried out according to the module-rating system, which consists of 2 content modules. The knowledge assessment system includes current, modular, and semester control of knowledge. The results of students' learning activities are evaluated on a 100-point scale. Forms of current control: assessment of tests, abstracts, oral answers during the lecture, written and oral independent assignments. The student can receive a maximum of 10 points for the evaluation of abstracts, oral answers during the lecture, written and oral independent assignments. Modular control: 2 modular tests, for which the student can get a maximum of 30 points (15 points for each work). The final semester control is conducted in the form of a test, during which the student can get a maximum of 40 points
