Hannes Bernien Labs
Quantum Science and Technology Atom-by-Atom
On June 3, 2025, Hannes Bernien and Hannes Pichler gave their inaugural lectures at the University of Innsbruck, presenting their research programs to a large and interested audience. Both physicists were jointly appointed by the University and the Austrian Academy of Sciences (ÖAW) and now serve as professors at the University of Innsbruck and scientific directors at the Institute for Quantum Optics and Quantum Information (IQOQI).
Our work on dual-species Rydberg arrays has been published in Nature Physics! Congratulations to the whole team! In the work we show the first Rydberg interactions between two atomic in an atomic array. There are multiple interaction regimes that can accessed and we demonstrate a strongly enhanced dual-species interaction via a Förster resonance. Further, we use the interaction to demonstrate a two-qubit gate and do quantum non-demolition measurements useing one atomic species as an auxiliary.
The BernienLab spent one week in Innsbruck to get to know their future environment. It was a fantastic week full of scientific exchange with the quantum community in Innsbruck, as well as social exchange. A picturesque hiking trip and a taste of the local cuisine rounded off a great trip. We will certainly come again!
Hannes has was awarded the Gordon Memorial Speakership at CLEO 2024. The award pays tribute to Jim Gordon's numerous high-impact contributions to quantum electronics and photonics
The BernienLab posts their latest work on the dual-species platform on the arXiv. In this work we introduce Rydberg interactions between the cesium and rubidium atoms in our arrays and explore new interaction and dynamic regimes that are unique to this approach.
