QSIT (HS 2012)

The lecture course Quantum Systems for Information Technology (QSIT) will be held in the fall term (HS) 2012. The course is presented as a set of two lectures complemented by excercises which are designed to give you a thorough introduction to both the theoretical foundations and experimental realizations of quantum information processing.

Lecturers: The lecture QSIT: Theory will be held by Matthias Christandl. The complementary lecture QSIT: Experiment will be held by Andreas Wallraff and supported by Stefan Filipp as a teaching assistant. A short summary of the contents of each of the lectures is provided below.

Attendance: The course is intended for Masters and doctoral level students or advanced Bachelor level students in Physics and related subjects. Basic knowledge of quantum mechanics as provided by the courses Physics IV, (new Physics III) , QM I (QM II) will be helpful to follow this course.

Course Selection: Ideally, you attend both lectures. If you have prior knowledge in either experimental or theoretical aspects of quantum information processing, you may also chose to attend either one of the lectures.

Course number:
