Possibly, you get to see some new devices, such as the ones shown below, on this occasion. The work I will be presenting was done at the Quantum Device Lab (qudev.phys.ethz.ch) of the Department of Physics, @ethz.ch Zurich and at the ETH Zürich - PSI Quantum Computing Hub. and the Quantum Center.

Looking forward to be attending the Superconducting Qubits & Algorithms (SQA) 2026 conference in Gothenburg, Sweden from August 25 to 28. I will be giving an invited keynote talk on the opening evening and present new work on #quantum error correction from our lab.

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.

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?

Gooooood morning #Switzerland! It is snowing! Where am I?

Andreas Wallraff @andreasateth.bsky.social · 31/05/2026

Also because of them Swiss Hockey has not lost a single game in this tournament! Check out the video below and use any footage for yourself, if you like! Hopp Schwiiz! I am keeping my fingers crossed for the first win of the team #Switzerland at an IIHF Hockey World Championship. Go and win this!

Andreas Wallraff @andreasateth.bsky.social · 31/05/2026

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.

I will be in the arena today for both the SUI-NOR and the CAN-FIN games. Say hello if you see me!

Andreas Wallraff @andreasateth.bsky.social · 30/05/2026

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.

We also analyze the overhead incurred by doing the computation blindly. Such methods could be used in the future over larger distances using either microwave or optical interconnects. (2/5)

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)

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...

Reaching 150 km/h is challenging. You probably fall at lower speeds than that and then slow down significantly.

Up for a race? I hear top speed is 150 km/h if you know what you are doing!
