JOB DESCRIPTION
The quantum nature of a physical system often emerges from its fundamental building blocks, such as atoms and molecules. In our group, we aim to establish coherent control of these individual quantum objects by advancing the recently realized combination of electron spin resonance and scanning tunneling microscopy (ESR-STM) [1]. ESR-STM allowed for example the coherent manipulation of single atom spins [2], addressing single atom nuclear spins [3] and high-resolution magnetic sensing [4,5]. This could recently be extended also to molecular spin systems [6]. The main goal of our group is to create a new solid-state architecture for magnetic sensing and quantum information processing operating on the atomic scale. During your work, you will gain practical experience in STM and related techniques, coherent manipulation of atomic spin centers, ultra high vacuum and low-temperature experiments as well as radio frequency (RF) electronics. You will work in a young enthusiastic team at the forefront of an exciting new field of research. Our new lab is fully running and has two unique mK ESR-STM machines which gives you the unique opportunity to take your next career step in a thriving and dynamic environment. Several research topics are possible:

• Coherent manipulation of atomic, nuclear and molecular spins on surfaces
• Developing new quantum sensors based on single atoms and molecules
• Instrumental development of our dilution refrigerator STM

The focus can be chosen depending on the preference of the applicant. The initial contract length is 36 months for PhD candidates (24 months for Postdoc candidates).

Interested candidates shall email a letter of motivation, a CV, and names and emails of up to two potential references to TTProf. Dr. Philip Willke (Philip.Willke@kit.edu). Shortlisted candidates will be continuously contacted until the end of the hiring period and will be invited for a remote or on-site interview and presentation.

EMPLOYER
The Karlsruhe Institute of Technology (KIT) is one of the largest scientific institutions in Europe. It is the only German university of excellence with a national large-scale research center combining a long university tradition with program-oriented cutting-edge research.
The university south campus is located in the heart of Karlsruhe, a young and vibrant city. It is well located in the heart of Germany and Europe, with less than one hour away from Frankfurt airport, less than 3 hours from Paris, and at the edge of the Blackwood forest as well as the Elsass. Karlsruhe is located in the state of Baden-Wuerttenberg, one of the hubs for innovation in Germany, making it an outstanding basis for your future career. Our research group on quantum coherent control of new atomic-scale spin systems, funded by the prestigious German Emmy-Noether Program, is based at the Physikalisches Institut at KIT, a vibrant center for a variety of quantum architectures. Within this environment we use scanning tunneling microscopy to study and control atomic scale quantum systems with cutting-edge technologies and instrumentation.
