Group Seminar at MPQ and via Zoom: Epitaxial Growth and Spectroscopic Investigation of the Strongly Correlated Compound Tm_xTe_y

While it is well known that strong spin orbit couplings and particular point groupe symmetries give rise to topologically non-trivial states of matter, a new approach is to investigate the possibility to find topological states of matter in strongly correlated compounds. more

Group Seminar at MPQ and via Zoom: Correcting coherent errors in quantum codes

Quantum error correction is a crucial step to building useful quantum computers, needed to maintain precision in deep computations in spite of having faulty components - as long as the error rate is below a threshold value. The most promising quantum error correction scheme to date more

Group Seminar at MPQ and via Zoom: Cavity assisted autonomous spin feedback

A reliable, flexible and repeatable method for quantum state preparation is crucial for all experiments in ultracold physics and can be achieved by autonomous stabilization of quantum systems. In this talk, I will present our recent results on stabilizing the collective spin of an atomic ensemble more

Group Seminar at MPQ and via Zoom: Creating Ultracold Gases of Dipolar NaCs Ground State Molecules

Ultracold dipolar molecules open up exciting prospects for quantum simulation, quantum computing, and quantum chemistry. The long-range dipole-dipole interactions between them offer new ways to engineer strongly correlated and highly entangled many-body quantum states. But creating and taming ensembles of ultracold molecules more

From inertial sensing to quantum computation, unlocking quantum advantages of ultracold atomic system requires ultra-precise single-body control of spinor matterwave. Such state-of-art controls are becoming closely achieved for quantum information processing with trapped ions. However, when applying these techniques to larger ensembles more

Group Seminar via Zoom: Ultracold RbCs molecules: Optical Tweezers, Lattices and Rotationally Magic Traps

The rich internal structure and intrinsic dipolar interactions possessed by polar molecules makes them a promising system for exploring quantum chemistry, quantum computation and quantum simulation. However, in order to enhance the impact of the polar molecule platform in these areas more

Group Seminar via Zoom: From simulating the trapping of cold atoms near a dielectric to solving an optimization problem

How to store quantum information ? How to perform quantum computation and how to rank the various technologies ? Trying to answer these questions, I got involved in various projects over the past two years. First, I developed Monte-Carlo simulations to study the feasibility and design more
