The Sonderforschungsbereich Designed Quantum States of Matter (DQ-mat) has been renewed for another funding period of four years. For mor details see the news-article at the webpage of the SFB.

Peter Micke succesfully defends his Ph. D. thesis. We congratulate him on this achievement.

The topic of his thesis is:

‘Quantum Logic Spectroscopy of Highly Charged Ions’

The HCI collaboration has just published an article in Nature on the quantum logic spectroscopy of ⁴⁰Ar¹³⁺. Congratulations!

Abstract: Precision spectroscopy of atomic systems is an invaluable tool for the study of fundamental interactions and symmetries. Recently, highly charged ions have been...

Our team members Maximilian Zawierucha from the MANFRED team and Tabea Nordmann from the QUACCS team share the second place for the best poster during the poster-session of PTBs PhD-Day (Doktorandentag). Maximilians Poster was on 'Quantum logic for high precision molecular ion spectroscop', and...

A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions

Kai Dietze joins the multi ion calcium spectroscopy team as a PhD student. He previsously already did his masters degree with us as a joint Student of Prof. Mehlstäubler and Prof. Schmidt, and recieved his bachelor's degree from Technische Universität Braunschweig. We welcome him to the team and are...

Kai Dietze receives his Master's degree. We congratulate him on this achievement.

The topic of his thesis is:

'Zustandskontrolle und Dynamical Decoupling mit Pulssequenzen für gefangene Ionen'

Compact physics package and fiber delivery of light for Al-Ca Quantum Logic Clock.
