In quantum mechanics measurement has a role going beyond just revealing preexisting properties of the observed system. Measurement is sometimes considered as signifying the transition from quantum to classical. In the seminar we will review different points of view of quantum measurement. Particular focus will be given to real measurements in the laboratory and their connection to the foundations of quantum physics.
This is an internal seminar for Professor Zeilinger's Group.

This course aims to explore the field of quantum optomechanics with a special emphasis on optically trapped atoms and levitated solid-state objects. Levitated optomechanics is at the forefront of research in quantum optics. The lectures will cover fundamental concepts and provide students with a firm grasp of the subject. In-depth calculations during the lectures will further deepen understanding of the most important concepts.
Contents: We will cover following topics in the lectures:
Week Topic
1 Fundamentals of cavity optomechanics: radiation pressure, optical cavity, harmonic oscillator, power spectral density
2 Classical theory of light-matter interaction: feedback and cavity cooling
3 Quantization of light and motion: input-output formalism, thermal bath model
4 Quantization of light and motion: interaction Hamiltonian, Langevin equations, ground state cooling, thermometry
5 Optical forces on neutral atoms
6 Optomechanics with levitated nanoparticles: Dispersive optomechanics
7 Optomechanics with levitated nanoparticles: Coherent scattering
8 Mode hybridization
9 Force sensing and fundamental physics
10 Hybrid optomechanical systems
11 Quantum effects: entanglement, squeezing, sub-SQL detection
12 Single-photon optomechanics
13 Student presentations

Method: Lectures and exercises will require active participation. Lectures will be supported (where possible) by demonstrations. Materials will be made available to students on Moodle.

Outcome: Students will get acquainted with research methods in quantum optomechanics. They will gain fundamental understanding of broad set of topics, which will allow them to conduct and discuss research.

Quantum mechanics, which used to be only a fascinating theory and an exciting approach to understand the nature, has now become a powerful tool to build new generations of sensors and detectors. Quantum sensors have a wide range of applications in various areas including communication technology, electromagnetic field sensing and biosensing. In the upcoming VCQ summer school, we aim to cover the basics of quantum sensing with photonic and solid state systems and our speakers will present state-of-the-art applications of such systems. After being introduced to the basics, participants will get to know the most recent advancements in quantum sensors and how they outperform classical counterparts.

When: from 6th till 10th of September 2021
Where: To be announced
ECTS-Credits: 3.00
