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.
We have an opening for a postdoctoral position to work on Experimental Quantum Computing with Trapped Rydberg Ions. The call will close on 20 September 2021. For complete information please follow the link to the official advertisement.
Our paper is published where we measure effects of the quadrupole polarizability of a single atom in a quadrupole electric field: Gerard Higgins, Chi Zhang, et al., Observation of second- and higher-order electric quadrupole interactions with an atomic ion, Phys. Rev. Research 3, L032032 (2021).
We have submitted our manuscript Gerard Higgins, et al., Micromotion minimization using Ramsey interferometry, 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.
