Evaluation: Final exam.
Prerequisites
QUANTUM or another course on quantum computing.
Presentation and objectives
The first part of the course will focus on several toipcs related to quantum cryptography and quantum information theory. We will in particular make an in-depth study of Quantum Key Distribution. The second part of the course will focus on quantum error correcting codes which is crucial for building quantum computers.
