Key experiments in quantum science and technology with photons, ions and atoms (MVSem)

Sommersemester 2025
Dozent: Schmitt J, Sturm S

Modern experiments have realised an extraordinary degree of control of isolated quantum systems. With a variety of experimental platforms, including photons, ions and neutral atoms it becomes possible to address the fundamental laws that govern quantum mechanics. A large toolbox has emerged that allows tackling different topics from high precision test of fundamental theories using single particles to quantum sensing and quantum simulation on few and many-body systems, up to the synthesisation of states of matter with a topologically nontrivial character. 

In this seminar we will discuss key experiments in this field. Each student will give a 30min presentation on one of the topics offered. The preparation of this presentation will include 2-3 meetings with the respective tutor to discuss the physics as well as the structure of the talk. Special emphasis should be devoted to the clarity of the experimental claims and techniques. After the presentation, a one-page summary should be provided. Further, it is expected that the students attend all presentations and participate with active feedback and questions. 

The seminar takes place on Fridays from 11:15 to 13:00. In the first seminar date (25/04/2024), we will give an introduction and each student will choose a topic. The topics will be announced after when the seminar is open for registration.
