We welcome Yannick to the Barium experiment! He studied physics at Erlangen and worked during his Master's thesis on a Quantum Communication platform based on coherent CV-QKD. Here in Innsbruck, his Ph.D. project will focus on fundamental Quantum Optics to study the interaction between a trapped ion and the single photons emitted by the ion in the presence of a hemispherical mirror.

Simon joined the group for his Master project where he will work on phase-modulated entangling gates for the AQTION setup. These promise to make entangling gates more robust to errors associated to fluctuating laser frequency and amplitude.

Armin joined the group for his Master project where he will set up a new 729nm laser system.

Anders did his master's degree at Stockholm University in the group of Markus Hennrich working on improving the coherence times of ions. In Innsbruck he will join the Quantum Information team on the LinTrap setup.

Stefan did his PhD at the TU Vienna in the group of Arno Rauschenbeutel. There he worked on a project showing theoretically end experimentally that the polarization state of light emitted by subwavelength emitters can give rise to a fundamental error in position measurements of the emitters. This work was published together with our former group members Gabriel, Daniel and Yves.

He is now joining the ERC project QCosmo from Philipp Schindler where he will apply quantum computing techniques to investigate polyatomic molecular ions.

For the first time, physicists from the University of Innsbruck have entangled two quantum bits distributed over several quantum objects and successfully transmitted their quantum properties. This marks an important milestone in the development of fault-tolerant quantum computers. The researchers published their report in Nature.

The new experiment will allow the scientists at the University of Innsbruck to explore new quantum electrodynamics effects by locating a single ion in front of a hemispherical mirror (Scilight article)

Congratulations, Marc!

Thesis Titled: Automated Frequency Locking via Spectroscopy on trapped ⁴⁰Ca⁺ Ions

Matthias did his Masters in Regensburg in the group of Prof. Schüller, and is now joining the Cryo team as PhD student. He will work both in Innsbruck and in Villach with Infineon on the development of novel 2D surface traps.
