Trapped Ion Quantum Technologies Group at Stockholm University

The group

Welcome to the Trapped Ion Quantum Technologies group led by Markus Hennrich. Our group is located at the Department of Physics at Stockholm University and is working on using trapped ions for quantum computation, quantum simulation and quantum sensing applications. In particular, we are one of only two groups worldwide that have realised trapped Rydberg ions - a promising technology for speeding up trapped ion quantum computers.

Postdoctoral and internship positions available in our group

Postdoctoral fellow in Experimental Quantum Computing with Rydberg Ions. ~~Closing date: 26 April 2023~~ Deadline extended to 10 May 2023. Please apply here.

Internship (paid and full-time) for an undergraduate student for 2-3 months this summer. The task is to build a delivery and stabilization system to send a laser beam between adjacent rooms. The student will gain valuable hands-on experience working with optics and lasers and gets an insight into the day-to-day work of a modern optical lab. More information and application here, closing date 5th of June.

Janurary 2023: Pre-print on Arxiv

Our pre-print on Single-shot measurements of phonon number states using the Autler-Townes effect has been uploaded on Arxivs: Marion Mallweger, et al., Single-shot measurements of phonon number states using the Autler-Townes effect, New J. Phys. 23, 123028 (2021), arXiv:2107.01902. In this work we introduce and demonstrate new techniques which allow us to minimize unwanted electric fields at the ions’ position fast and precisely via interferometric pulse sequences.
