Quantum Engineering and Information

Teachers : Stephane Guerin / Hans Rudolf Jauslin / Christophe Couteau

This course proposes an introduction to the basic concepts and techniques of quantum information, quantum computation and, more generally, of quantum technologies.

The concept of quantum technologies encompasses a family of processes that use quantum effects to produce results that are not possible or more difficult with classical physics. In quantum computation quantum mechanics is used to design algorithms that achieve certain results much faster than classical algorithms.
