In recent years, a quantum mechanical theory of information has emerged. It is based on the idea that, ultimately, all processing of information requires physical objects to carry it. If implemented microscopically, the quantum mechanical nature of the carriers needs to be taken into account. This new perspective not only imposes restrictions but also opens up new, classically unexpected ways to process information.
The first part of the module will present quantum mechanics in finite-dimensional spaces where most of quantum information processing takes place. Concepts such as general measurements and entanglement will be introduced. The second part will focus on quantum information proper, i.e. on quantum circuits, teleportation, and basic but surprisingly efficient quantum algorithms. Other topics such as quantum cryptography, error correction, other quantum algorithms, or the subtle properties of entanglement will be discussed if time permits.
Coursework (10%) plus 120 min closed examination in Wk 1 of the Spring Term (90%). Note that coursework submitted after the advertised deadlines will be given a mark of zero.
This module introduces the theory of quantum information. After a self-contained presentation of non-relativistic quantum mechanics in finite spaces, basic paradigms of the theory of quantum information proper will be discussed.
Please check prerequisites carefully before asking to take this module as an elective.
