Design and dynamical control of artificial quantum systems for quantum computation and simulation

Event Description



The spectacular developments and control of artificial quantum systems hold the potential for quantum computation and the solution of complex quantum many-body problems ranging from quantum chemistry, condensed matter systems to high energy physics. Many explored quantum computing and simulation platforms use two-level systems as building blocks. However, artificial quantum systems can also be created from multi-level systems as constituents, allowing us to move beyond qubit-based quantum computation and simulation architectures. In this talk, we discuss how the multiple levels constituents can be harnessed to design novel platforms with a natural quantum error correction scheme. Secondly, we explore how periodic drive enables us to dynamically generate symmetries for quantum simulation. Finally, we explain how combining multiple levels and dynamical control opens the door for creating important entangled quantum many-body states as they appear, for example, in quantum error correction and lattice gauge theories.


Valentin Kasper is currently a La Caixa Junior leader at ICFO - The Institute of Photonic Sciences - in Barcelona after starting as a Marie-Sklodowska-Curie fellow in the quantum optics group of Prof. Maciej Lewenstein. Previously, he was a Feodor-Lynen fellow at Harvard University, where he worked in the condensed matter theory group together with Prof. Eugene Demler and Prof. Subir Sachdev. He obtained his Ph.D. from the Ruprecht Karl University of Heidelberg in 2016 under the supervision of Prof. Jürgen Berges and performed his undergraduate studies at the Otto-von-Guericke University Magdeburg. His research interest is at the intersection of theoretical quantum optics, quantum many-body physics, and quantum information processing. Recently, his research has focused on novel designs and usage of artificial quantum systems for quantum computation and simulation.
