Lectures, Seminars and Lab Courses

University of Vienna

Lecture+Exercise

260132 VU Qubits, Spins and Quantum Sensors

Lecturer(s): Michael Trupke, Kahan Mcaffer Dare

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.

When:

Wednesday, 16:00 - 18:15

Where:

Seminar room Physics, Sensengasse 8, ground floor

ECTS-Credits: 5.00

Lecture+Exercise

442614 VU Modern Foundations of Quantum Mechanics

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

Lecture+Exercise

260799 VU Quantum Information Theory I

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.
