Lecture: Foundations of Quantum Mechanics

Lecturer: David Gross. Exercises: Vahideh Eshaghian


  • Some students have reported that they cannot sign up in the KLIPS system. Don't worry. Just show up.

Course description

The course will cover the properties of quantum mechanics that are fundamentally different from any classical theory. This contrasts with the usual QM classes, where the goal is to treat specific systems; and with Quantum Information Theory, where the focus lies on ways to exploit quantum behavior for computation and communication.

Topics are:

  • Contextuality, Bell inequalities, and "quantum non-locality"
  • Causality and its interaction with quantum probability
  • Uncertainty relations and their interpretation
  • The problem of joint measurability
  • No-cloning
  • Generalized Probabilistic Theories, post-quantum correlations and their convex geometry
  • Measurement theory and decoherence
  • Projective representations of symmetries


  • The lecture is good for 6 ECTS points and will fit into the GR/QFT and the CM/CP areas of specialization.
  • Dates, time, venue: Mondays at 12pm, Tuesdays at 10am. Seminarraum 0.03, Theoretical Physics New Building, Zülpicher Str. 77a.
  • We will aim to provide a life Zoom stream and will also post recordings online. Links will be provided later.
  • Every second week, the Tuesday slot will be an exercise class.
  • This lecture was held before.
