Thanks to Quentin Ficheux from @cnrs.fr for being his co-adviser and co-examiner on the defense and Leonardo Degiorgi for chairing the exam.

Congratulations to Dante Colao Zanuz for passing his PhD exam at the Department of Physics of @ethz.ch. Dante did his research work on the fabrication of superconducting circuits for #quantum information processing at our Quantum Device Lab which is part of the #Quantum Center of ETH Zurich.

Thanks to Alexandre Blais from Institut quantique - Université de Sherbrooke for being his co-adviser and co-examiner on the defense and Leonardo Degiorgi for chairing the exam.

This was not the plan for my trip to Erlangen with Deutsche Bahn.

A degree for the quantum age In 2019, ETH Zurich launched one of the world’s first Master’s degrees in Quantum Engineering. Since then, interest in the programme has soared – and its first graduates are already making their mark…

Read this nice article on our #Quantum #Engineering Master program at ETH Zurich.
It is currently featured on the ETH main web entry page.

Goooooood morrrrrnnnning from #Schatzalp, #Davos, #Switzerland. the site of this year's ETH #Zurich Quantum Center Retreat.
Great to meet all our ETH Zürich #quantum researchers here for a few exciting days.

Interesting color of lake #Zurich today!
First post heat wave day.

Mmmmm!

Enjoying the weekend football/soccer matches at the ASVZ pitches at either the ETH Hoenggberg campus or the Fluntern facility.
Thanks to Claudio for organizing since many years. Is it more than 10 years already? It started out with a mostly ETH Physics crowd originally, but a very mixed group now.

Celebrating the 2D Cluster State paper with a home made cake by Kevin.
Well done!
