Over the past two decades, the rapid evolution of quantum systems engineering has paved the way to new forms of processing and transmission of information. At the crossroads of quantum mechanics, computer science, information theory and engineering, the development of quantum computers allows to consider solutions to problems that seemed impossible to solve with a classical approach. The objective of the course aims at understanding the challenges linked to the developments of quantum information and at perceiving in what extent they can modify the current landscape of information processing.
