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?

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.

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)

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]

Looks like our Circuit Quantum Electrodynamics (or short Circuit QED) Review (@apsphysics.bsky.social American Physical Society, Rev. Mod. Phys. 93, 025005 – Published 19 May, 2021) got the first 2000 citations. At least that is what Google Scholar claims. [1/3]

I think I took a photo of a two-level defect, also known as a TLS, at the QEC25 conference on #quantum error correction at Yale and @yaleqi.bsky.social today. Are there any experts on superconducting circuits out here to confirm or deny?

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.
