PhD Position/PostDoc Position: Quantum Coherent Control of Atomic and Molecular Spin Centers in an STM

Job type: 

Application deadline: 

Thursday, December 31, 2020

The quantum nature of a physical system often emerges from its fundamental building blocks, such as atoms and molecules. In this project, 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]. The main goal of this project 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 jump starting now 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
• Setting up and start of operation of a 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 Dr. Philip Willke ( Shortlisted candidates will be invited for a remote interview and presentation.

The Karlsruhe Institute of Technology (KIT) is “The Research University in the Helmholtz Association”. As 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. At KIT, more than 5000 scientists work together on a broad disciplinary basis in the natural, engineering, economics, humanities, and social sciences.
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.
