### Seminar

#### Device-independent Physics (260078)

Professor(s): Miguel Navascues

When physicists do not trust the calibration of the devices composing an experimental setup, they can opt to model the whole experiment via a black box, where one inputs a symbol (the type of experiment) and returns an output (the outcome of the experiment). Remarkably, in some situations, the mere correlations between different laboratories (or boxes) allow one to learn something meaningful about the contents of each box. E.g.: assuming that the system inside the box is quantum, correlations between different boxes are enough to lower bound the Hilbert space dimension of the underlying quantum state. Morever, since different physical theories predict different possible correlations between distant observers, some of such “device-independent” experiments can reveal the nature of the system within the black box. In this course we will learn what makes correlations physical (classical, quantum or otherwise) and how different assumptions on the underlying experimental setups translate at the level of correlations.

### Lecture

#### Entanglement theory (260063)

Professor(s): Yelena Guryanova, Marcus Huber, Maximilian Lock

Goal of the lecture is an in-depth exploration of the phenomenon of quantum entanglement. Initially regarded as a mathematical artefact with, at most, philosophical implications, recent years have seen the rise of quantum information theory with entanglement as a fundamental resource for information processing. In this lecture we will cover the basics and historical development of understanding this phenomenon, continuing to modern entanglement theory of bi- and multipartite systems. We will discuss mathematical methods for its characterisation, quantification and certification and connect to some modern applications to give a comprehensive overview over the field of entanglement theory.
