TECHNOLOGIES of QUANTUM INFORMATION

The course will provide basic notions, from quantum mechanics to elements of the theory of solids and quantum transport, necessary to the understanding of modern quantum technologies. Phenomena and principles at the basis of Quantum Technologies will be reviewed as well as applications. The goal is to provide the student with skills and competencies complementing the the basic microelectronics curriculum, as: (a) familiarity with the emerging opportunities that nanoelectronics and quantum technologies offer; (b) ability of using quantum mechanics in different contexts of ICT and Nanotechnologies and judging the state of the art and relative progress in different technologies involving nanosystems; (c) acquiring a basis to come up with their own idea of new interesting project.

The present course addresses the multidisciplinary need of the diverse industrial sectors embracing nowadays nanotechnology, and the recent growth of interest in quantum technologies, which may offer new opportunities for employment and specialization to our graduates.

The student must have elements of the language, as a good knowledge of classical physics and some grasp of introductory device physics.

The course is divided in three parts, namely (1) basic quantum mechanics and solid state physics, and (2) applications to quantum technologies.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out online, should the conditions require it.
