Recommended Prerequisites

Quantum Mechanics and Optics.

Teaching Methods

Some of the topics will be addressed in an expository way, others will be proposed to the student for autonomous development, after a brief introduction in class. Some problems at home will require using the IBM quantum computer. Students should consult a specialized bibliography on some of the topics covered by the program and present orally an article of their choice.

Learning Outcomes

Physical basis of systems used in quantum information, namely those based in magnetism, superconductivity and quantum optics. Description of some quantum based technological devices. Modeling and solving problems using the IBM quantum computer. Ability to search bibliography and present a recent paper to an audience. To be familiar with the frontiers of research in quantum technologies.
