Quantum Optics and Quantum Information

Recommended Prerequisites

Portuguese, or English if there is at least one non-native speaker in the room.

Teaching Methods

This course will combine theoretical and exercise problem sheets in such a way that the student can acquire the techniques to investigate Many-Body Systems. The concepts will then be worked out by the study of applications always present during the course.

Learning Outcomes

The main goal of this course is to provide in-depth knowledge of Physics in the field of quantum optics and its technological applications, quantum computing and quantum information.
