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 openings for one PhD and two Postdoc positions:
Our paper on Micromotion minimization using Ramsey interferometry has been published in New Journal of Physics: Gerard Higgins, et al., Micromotion minimization using Ramsey interferometry, 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.
European Conference on Trapped Ions (hybrid ECTI 2021) hybrid conference is held as an online event with satellite meetings in Oxford (22 Nov) and Mainz (25 Nov).
The conference brings together the European and international ion trapping communities and will cover topics in quantum computing and quantum simulations, quantum networks, precision measurements and optical clocks, molecular ions and atom-ion mixtures, non-neutral plasmas, novel approaches, and more.
