An Introduction to Quantum Computers — •Norbert Schuch — Max-Planck-Institut für Quantenoptik, Garching, Germany

Quantum computers use the laws of quantum mechanics to carry out computations much more efficiently than classical computers. This lecture will provide an introduction to the theory of quantum computers, assuming only basic knowledge of quantum mechanics. I will explain how quantum superpositions can in principle be used to speed up computations by quantum parallelism, why it is yet so challenging to find new quantum algorithms, and which promises make quantum computers such an exciting topic. Throughout, the discussion will be guided by simple examples of quantum algorithms. Towards the end, I will also briefly discuss how quantum computers can be made robust against noise.
