We are developing a microwave ion trap capable of confining ultra-cold plasmas. The main long-term objective is to cool the electrons so much that they de-localise over several ions in a Coulomb crystal stored in a Paul trap. Such a quantum-mechanical system shall be used as quantum gates in the future. Still, we are mainly interested in interactions of the quasi-free electrons with the external electro/magnetic fields.

The group was founded in 2021 by a PI with experience designing Paul traps. Our key achievements so far are the improvement of the glass-based circuit board manufacturing method. We are in the last stages of building a microwave Paul trap for trapping electrons. This is expected to be operational in 2023.
