@g8ge Yes, on Wednesday night at 8 pm.

Will there be a hockey game?

Welcome to the American Physical Society @APSphysics Global #Physics Summit #APSSummit26, also known as the APS March Meeting #APSmarch, in #Denver this year. I just have arrived! Check out the updated program of our @qudev lab's contributions to the #conference and also the information on where to attend the #Quantum #Hockey Match by following this link: lnkd.in/dYEzV_n8 P.S.: Anyone taking a selfie at the APS logo will have the butt of a big blue bear in the background.

Success!

Special luggage. Where am I going and what for? Also will Swiss and Air Canada manage to loose my gear again?

Progress.

Hmmmmmm ….

The arXiv is becoming a nonprofit separate from Cornell, and they're looking for a CEO. Please repost to let good candidates know! @quantum_aram @michael_nielsen jobs.chronicle.com/job/37961678/c…

Progress!

Should I start to be worried?

First time!

Exciting #hockey match at the #Olympics2026 between the #Canada and the #USA. Not #quantum hockey, but still. @APSphysics

Great start for #Switzerland 🇨🇭into the #Olympics !

Concerned about #quasiparticles in your #superconducting #devices? In this new @arxiv manuscript entitled "Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation" we share some of the insights we have gained while doing experiments on the topic in our lab: arxiv.org/abs/2602.05806… . Share your experiences with us, if you have any! Curious to hear about them. The work was done by @KerschbaumMi, Felix Wagner, Uroš Ognjanović, Giovanni Vio, Kuno Knapp, Dante Colao Zanuz, Alexander Flasby, Mohsen Bahramipanah, @AndreasAtETH, and Jean-Claude @BesseJC at the Quantum Device lab @qudev, the Quantum Center @ETHQuantumCntr, and the @ETH_en Zürich - @psich_en Paul Scherrer Institut #Quantum Computing Hub with support from the State Secretariat for Education, Research and Innovation @SBFI_CH, @IARPAnews, the @ETHFoundation1, and @ETH Zürich.

And some coverage in a News&Views article in @NaturePhysics written by Murphy Yuezhen Niu : nature.com/articles/s4156…

Need to perform surgery on your logical #qubits? Here is how to do it with #superconducting #circuits. With lattice surgery you can entangle logical qubits, which is a step required for realizing two-qubit gates between logical qubits. This is particularly useful when the qubits are laid out in a square grid. Check out our lab's new paper "Lattice surgery realized on two distance-three repetition codes with superconducting qubits" which appeared as an open access publication in @NaturePhysics today: nature.com/articles/s4156… The paper is also available on @arxiv as arxiv.org/abs/2501.04612 . The work was done at the @ETH_en Zürich - @psich_en Paul Scherrer Institut #Quantum Computing Hub and the Quantum Device Lab of the Department of Physics (@ETH_physics), @ETH Zurich in a collaboration between Ilya Besedin, Michael Kerschbaum, Jonathan Knoll, Ian Hesner, Luca Hofele, @NathanLacroix , Christoph Hellings, @FrancoisSwiadek, Alexander Flasby, Mohsen Bahrami Panah, Dante Colao Zanuz, and @AndreasAtETH Wallraff at ETH Zürich, the Quantum Center, ETH Zurich, and the ETH Zürich - PSI Paul Scherrer Institut Quantum Computing Hub and Lukas Bödeker, Luis Colmenárez, PhD and Markus Müller at the @fz_juelich Forschungszentrum Jülich and @RWTH Aachen University. The work was supported by @IARPAnews, by the State Secretariat for Education, Research and Innovation @SBFI_CH, by Innosuisse, by the @ETHFoundation1 and by @ETH Zürich.

@JFCarew 10 mK!

@AndreasAtETH So cool!
