Enjoying my 40 USD surcharge ‘window seat’ on my delayed United flight from LAX to SFO. So no photos out of the window, I guess. Special service for Star Alliance members.

Research and education in physics with a focus on quantum computing, communication and sensing with team Qudev (https://qudev.phys.ethz.ch/) at ETH Zurich. Team lead at the ETHZ-PSI Quantum Computing Hub. Director of the Quantum Center at ETHZ.
Having a great time at the UCLA #Quantum #Device Workshop with Mollie Schwartz, the internet sensation @zlatko-minev.bsky.social, and the UCLA bear. Check out the program here: qdc-qcsa.org/qdw/2026/info . It is never too late to learn more about quantum science with superconducting circuits.
I am heading out to the #Quantum #Device #Workshop at #UCLA. Last year it was a super fun event. Looking forward to meet students and colleagues there. Find out more about the program and the other contributors here: qdc-qcsa.org/qdw/2026/info Will you be attending in person or online?
Check out this hot off the press article in the @nytimes.com on our work on #perfect #randomness : www.nytimes.com/2026/06/09/s... The work was done at Department of Physics, the #Quantum Center @ethz-qc.bsky.social , and @ethz.ch #Zürich ...
A Scientific Achievement That’s Totally Random

I am optimistic that #Switzerland will win against #Finland tonight at the @iihf.bsky.social #Hockey World Championship in #Zurich. If anything, it will be almost impossible to win against this crazy crowd of 10 thousand #Switzerland supporters in the very nice SwissLife Arena.
Hopp Schwiiz! I think #Switzerland is moving on to the finals today in the @iihfhockey.bsky.social #hockey world championship semi-final game against Norway. The Swiss team is doing a great job and the atmosphere in the Arena in #Zurich is amazing with 10.000 supporters. Check out the video below.
For all German speakers, here is 6 minute piece in @deutschlandfunk.de.web.brid.gy , one of the big German radio stations, on our work on generating perfect random numbers using #quantum #physics. Check it out here: www.deutschlandfunk.de/perfekter-zu...

Are you in need of some certified #randomness? Check out our newest paper entitled "Experimental randomness amplification" which appeared in @nature.com today. www.nature.com/articles/s41...
Do you wonder how you can execute a #quantum algorithm on a quantum server in a way that the operator of the server does know neither the task nor the result? Here we conceptually demonstrate blind quantum computing using two modules on a modular 3D integrated #superconducting #circuit. (1/5)

Full house for the 2026 #Quantum #Hackathon organized by the Quantum Engineering Commission at @ethz.ch #Zurich. With a welcome note the Rector of ETH Zürich and by Manjari Sengupta the president of the Quantum #Engineering Commission Check out the program here: qec.amiv.ethz.ch/qhack26/
This year our Quantum Device Lab (qudev.phys.ethz.ch) has completed its first 20 years at the Department of Physics of @ethz.ch Zürich, since 6 years we are also part of the Quantum Center, @ethz-qc.bsky.social, and since 5 years we co-run the @ethz.ch Zürich - @psi.ch #Quantum Computing Hub. ...
Found a new favorite #coffee place near @ETH_en #Zurich and the University @UZH_en in #Zurich, #Switzerland. It's called #Hype but it is no hype. Check it our. maps.app.goo.gl/avqfgqq8aVva...
Extremely happy with this collaboration, that started with the EU project Superqulan and culminated with a very nice demonstration of photon mode multiplexing in quantum links, led by @andreasateth.bsky.social's group at ETHZ arxiv.org/abs/2604.129...
Special luggage. Where am I going and what for? Also will Swiss and Air Canada manage to loose my gear again?
Up for a race? I hear top speed is 150 km/h if you know what you are doing!
Gooooood moooorrrrnnnning from … Mönch, und Jungfrau. Doing some skiing today. Maybe participating in the Slalom race spontaneously. Where am I?
Goooooood moooorrrrning. Do you recognize this place? Any guesses on what I am here for?
Bon appetit. More food pics from my holiday cooking adventures.

Got back to doing some cooking over the holidays! These are meat balls with a spicy tomato-pepperoni-ginger sauce which turned out very nice. I have not posted any food pics in a while! Are you still into it?
Do you find it challenging to accurately control the transition frequency of your superconducting #qubit by applying magnetic flux? Frequently, the frequency dependence of the response function of the electronics, the wiring, and the flux-bias circuitry must be compensated for to accurately .. [1/7]
Five years ago at the @qudev Lab of ETH Zürich we have reported on the first realization of a "Microwave #Quantum Link between Superconducting Circuits Housed in Spatially Separated Cryogenic Systems" coupling #qubits across a distance of 5 meters through a #microwave waveguide. [1/5]
This is a beautiful place! Do you know where this is? And what I am here for?
Just in time for the start of the new fall term 2025, our Quantum Device Lab's new and improved web site is available. Go and check it out here: qudev.phys.ethz.ch With an updated list of publications: qudev.phys.ethz.ch/publications ...
