Elements of quantum information theory

In the two lectures I will go through elements of quantum information
theory that are potentially useful also in other research fields.
- Density operators and partial trace (short refresh)
- Purification
- Principles of deferred and implicit measurement
- Quantum operations and Kraus operators
- Fidelity and trace distance
- Holevo bound

Lecture notes.

This event is part of the master lecture series organized by the Section for Theoretical Physics.
