Summerschool 2022

This year the summer school was organized by a PhD student researchers team and contained seminar talks by five invited lectures which covered the research areas of AMO physics like astrophysics, spectroscopy, quantum simulation, quantum computation, quantum optics, and quantum information. Furthermore, the poster session allowed the PhD student researchers to present their research.

We thank the speakers of the summerschool for giving excellent talks and seminars on hot topics in AMO physics and for stimulating questions and discussion with and among the students.

Optimizing quantum state control in a two-level system

The two-level system is a fundamental concept in quantum technologies. It can act as qubit for a quantum computer or as photon source for quantum communication. Therefore, it is essential to understand how to manipulate it. When realized in a solid, the dynamics of two-level systems is modified by their interaction with the crystal matrix. After reviewing the basics of the
two-level system, we will discuss how the interaction with the environment leads to decoherence. At the example of a semiconductor quantum dot, several manipulation schemes shall be compared, showing that sometimes even the simple two-level system can bear surprises.

Andreas Osterwalder, EPFL

Introduction to reaction dynamics

This lecture will focus on the basics of chemical reaction dynamics. In the gas phase, crossed molecular beam studies provided key insight in the fundamentals of such processes, and this was recently expanded to low energies through the development of the merged neutral beams method, which now is also combined with stereo dynamics. On the other hand, chemical dynamics at liquid interfaces is much less well understood and, in particular, nearly no experimental data is available on the scattering of
gas-phase molecules on volatile liquids like water.

David Gross

Introductory lectures to quantum computing

I will introduce the theory of quantum computations. We will look at how information is being processed in a quantum circuit and discuss quantum search algoirthms - a counter-intuitive but easy to understand class. No prior knowledge beyond standard quantum mechanics is expected.

Serge Krasnokutskiy

Chemistry of the interstellar medium with an emphasis on the formation of organic molecules

I will give a lecture on the chemistry of the intestellar medium with an emphasis on the formation of organic molcules. The first part of the lecture will be  devoted to the chemical and physical processes occurring in the interstellar, and the  second part will be devoted to laboratory studies of these processes.

Peter Lodahl

Deterministic photon-emitter interfaces fundamentals and applications

Semiconductor quantum dots embedded in photonic nanostructures offer a highly efficient and coherent deterministic photon-emitter interface. It constitutes an on-demand single-photon source for quantum-information applications, enables single-photon nonlinear optics, and the constructing of deterministic quantum gates for photons. We review the fundamental operational principles of deterministic photon-emitter interfaces. We discuss the generation of photonic resource states such as high-quality single photons, multi-photon entanglement sources, and photonic quantum gates based on nonlinear single-photon interaction. Finally we discuss potential applications of this novel hardware for device-independent quantum key distribution, one-way quantum repeaters, and photonic quantum computing

Matthias Kleinmann - absence due to illness

Nonlocality is a fundamental feature of quantum theory which first has been discussed as an unfavorable property of quantum theory, then was experimentally verified, and now has important applications in quantum cryptography. I will give a tour through quantum nonlocality, the monumental task to conclusively violate Bell inequalities, and the applications that came out of all this
