Lecture

Experiments in Quantum Optics and Quantum Information (260075)

Professor(s): Markus Arndt, Philip Walther

The goal is to obtain a profound introduction to concepts and experiments in modern quantum optics and quantum information processing. The lecture can be attended without prior attendance of the course on theoretical methods of quantum optics and quantum information. But it is highly recommended to participate in both (in any sequence).

Lecture

Theoretische Physik III für das UF Physik (267232)

Professor(s): Beatrix Hiesmayr, Brigitte Waldmann

Der Zyklus “Theoretische Physik für das Unterrichtsfach” legt den Fokus auf die logische Struktur der Physik und ihre Erkenntnisse, wobei der mathematisch-technische Schwierigkeitsgrad niedrig gehalten wird. Er schafft schulrelevantes Orientierungswissen und Überblickswissen, das zukünftige Lehrkräfte dazu befähigt, Fragen der Schülerinnen und Schüler richtig einzuordnen und bei der Zielsetzung der Unterrichtsplanung hilft. Im Rahmen dieser Lehrveranstaltungen sollen Lehrkräften die Arbeits- und Denkweisen der Physik und das Wissen über die großen offenen Fragen der modernen Physik vermittelt werden. Es wird empfohlen die Module des Zyklus „Theoretische Physik für das Unterrichtsfach“ der Reihe nach zu absolvieren.

Quantum Information Theory I (260799)

Lecturer(s): Beatrix Hiesmayr

This event gives an introduction to quantum information theory mainly from the theoretical point of view but with relations to experimental feasibility. Any formidable Quantum Computer will take advantage of superposition and entanglement which are the focus of the course. In detail, you will learn about geometrical representations of the state space of two-level systems (qubits) and higher-level systems (qutrits/qudits) and systems containing more than two particles; about classification and detection of entanglement in bipartite and multipartite systems; what different kinds of information quantum systems offer compared to classical systems; about a magic state space allowing to understand applications of quantum information theory such as Bell inequalities, distillation or teleportation; about how to address detection of entanglement via powerful frameworks and their experimentally feasibility. All this are key ingredients for quantum computing and quantum machine learning. Depending on the wish of the students it will be either in English or German.

Modern Foundations of Quantum Mechanics (442614)

Lecturer(s): Caslav Brukner, Luis Cortés Barbado

Even after more than 90 years of quantum mechanics the researches have not reached a consensus on what its philosophical and epistemological implications are. A prerequisite for understanding quantum theory is to learn about various failures of explaining quantum behaviour on the basis of the classical notion of reality. This course focuses exactly on this point: what quantum mechanics is not. The lectures and accompanying exercises provide a theoretical minimum for working on quantum foundations as an independent researcher, including all the necessary background knowledge from quantum theory.

Topics: Einstein-Podolsky-Rosen paradox, Kochen-Specker theorem, Bell’s theorem, non-local boxes, non-local and no-signalling correlations, no-go theorem for finite-speed influences, non-extendibility of quantum theory, Pusey-Barrett-Rudolph theorem, no-go theorem for finite information content in a quantum system, and no-go theorem for observer-independent facts.

Qubits, Spins and Quantum Sensors (260132)

Lecturer(s): Michael Trupke, Kahan Mcaffer Dare

The Lecture „Qubits, Spins, and Quantum Sensors“ is an introduction to a selection of key topics in quantum technology, with a focus on spin-based systems such as the nitrogen-vacancy centre in diamond.

Content:The lecture will comprise the concept of a qubit, some of its physical implementations and the core applications of such systems. The description of applications will include an overview of quantum computation, quantum communication, and quantum sensing. A particular focus of the description will be placed on electronic and nuclear spins in semiconductors such as diamond, silicon, and silicon carbide. This focus will allow to underline the connection between quantum technology and “classical” nuclear magnetic resonance as well as electron spin resonance methods. The course will outline the astounding technological and conceptual progress of the field in the last decades, examples of current research directions, and existing commercial pursuits.

Far from equilibrium dynamics: memories, engines and chaos (260137)

Professor(s): Thomas Nikolai Kiesel

The aim of the course is to provide insight into state-of-the-art topics of non-equilibrium thermodynamics and its underlying principles. Specific examples include:- how the fundamental link between information and thermodynamics relates to the operation of memories- how a single particle undergoing Brownian motion can be used to explore fundamental limits of operating engines in the classical and quantum regime- how we can get a deeper understanding of the meaning of the 2nd law and the thermodynamic arrow of time.Each student will, with the help of a supervisor, prepare an oral presentation on a specific topic. In addition, students will be provided questions and literature to prepare for a moderated debate on deeper topics within the seminar.
