Independent learning






  1. Students should know the basic quantum mechanics and quantum information theory as provided in the MSc. 

  2. Further recommended knowledge: probability theory. 



Competences to be gained during study


  1. Understanding one-shot information processing tasks

  2. Understanding the mathematical tools to analyse one-shot protocols





Learning objectives


Referring to knowledge

  1. Broad perspective of quantum information theory, especially one-shot information theory. 

  2. Become familiar with the basic tools of formalism: min- and max-entropies, Rényi entropies and relative entropies

  3. Understand the basic tasks and protocols; decoupling, hypothesis testing, convex-split lemma, position-based coding.
