This lecture gives an introduction to quantum information theory and theory of open quantum systems. The lecture is accompanied by exercises and bi-weekly tutorials.

Topics include:

  • Recap of basic quantum mechanics: Postulates, qubit systems, density matrix
  • Quantum measurement
  • Quantum entanglement
  • Schmidt decomposition and purifications
  • EPR paradox and Bell inequalities
  • Quantum channels
  • Distance measures between quantum states
  • Classical and quantum entropy
  • Quantum thermalization
  • Lindblad Master equation

Dates and rooms: Lecture Mondays 14:15-16:00 starting on 25.04.2022. Room: Philos.-weg 12 / kHS. Tutorials biweekly on Tuesdays 14:15-16:00 or Wednesdays 14:15-16:00.

Prerequisites: Solid knowledge of quantum mechanics (PEP3+PTP4). Theoretical Quantum Statistics or Introduction to Quantum Science and Technology is very useful.

Mode of examination: The grade will be based on a written exam.



General literature:

  • Nielsen and Chuang: Quantum Computation and Quantum Information (Classic textbook. We will focus on the quantum information part)
  • Watrous: The Theory of Quantum Information (Comprehensive introduction to quantum information theory, rather formal/mathematical, including some more specialized concepts)
  • Wilde: From Classical to Quantum Shannon Theory (Very comprehensive introduction to classical and quantum information theory, focus on coding and data compression, data transmission)
  • Lecture notes by John Preskill: 1-4 and 10) and corresponding videos:

Lecture 8:

Nielsen and Chuang, Chapter 12.5

Review article on entanglement:

Review article on entanglement measures:

Lectures 9/10:

Nielsen and Chuang, Chapter 11

Note that there is a sign error in lecture notes 10: In the proof of subadditivity, in the second line, there should be a minus sign in front of S(rho_AB). The subsequent line is correct again.

Lecture 11:

Nielsen and Chuang, Chapter 12.1

Review article: From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics. Luca D'Alessio,Yariv Kafri, Anatoli Polkovnikov and Marcos Rigol.
