Practicing your march meeting talk already? Time to sharpen your skates as well! Less than six weeks to go to this year's @APSphysics American Physical Society Global Physics Summit 2025 (also known as the #APSMarch Meeting). As in previous years, this will also be the occasion of the epic showdown between the two famous #quantum #hockey teams The Mighty Atomic Strike and The Superconducting Lightning. You are invited to participate as a player or a spectator. Thanks to Niki, we have reserved time for a two hour skate on Tuesday, March 18, from 7.45 to 9.45 pm at the Anaheim ICE Rink ( which is only 2.5 miles from the conference center. Let us know, if you want to join and sign up here: Spread the word and motivate your friends to play or watch the game. Check out the photos from past games at the #APSmarch Meeting. Previously players from @IBM, @meetIQM, @QueraComputing, @rigetti, @BlueFors_Ltd, @Harvard University, @ETH_en, @Zhinst, @quantumWMI, @QuTech_news, @Yale_QI, @IQ_USherbrooke and many more joined. Go and join them this year!

Had a great time in Washington DC with our SuperMOOSE team at the @IARPAnews Entangled Logical Qubits Technical Exchange Meeting. Great work everyone. Exciting presentations by all teams. @MIT @AtlanticQuantum @Zhinst @fz_juelich @RWTH @IQ_USherbrooke @USherbrooke @ETH_en @ETH_physics @ETHQuantumCntr @qudev

The now exhausted organizing committee of the 2025 @APSphysics #APSMarch Meeting #Quantum #Hockey Match met today at the @MIT #hockey rink to plan this year's game. Are you excited about it and interested in joining the match? Watch out for more information in this space and spread the word! The committee members are from @Harvard @harvardphysics, @ETH_en @ETH_physics @ETHQuantumCntr, @QueraComputing, and more.

Looking forward to be at @Harvard today to give a @harvard_quantum Initiative Special Colloquium on Realizing Lattice Surgery on Two Distance-Three Repetition Codes with Superconducting Qubits (. Details are available here: Looking forward to see you there. @harvardphysics @hseas @qudev @ETHQuantumCntr @ETH_physics @ETH_en @psich_en

Check out our Quantum Device Lab (@qudev) paper published five years ago in which we demonstrated the realization of a single-shot, quantum-non-demolition parity detector for #microwave #photons. With this detector we have performed Wigner #tomography of propagating microwave fields. We have also used it to herald propagating Schrödinger cat states when projecting a coherent field into one with a set parity. More details are available in the paper entitled "Parity Detection of Propagating Microwave Fields" published in the @APSphysics journal @PhysRevX 10, 011046 on 26 February, 2020: The work was done by Jean-Claude Besse (@BesseJC scientist at ETH Zürich), Simone Gasparinetti (now professor at @chalmersuniv University of Technology), Michele Collodo (now at @Zhinst Zurich Instruments), Theo Walter, Ants Remm (now at @AtlanticQuantum), Jonas Krause (now at German Aerospace Center (@DLR_en), Christopher Eichler (@eichler__chris now Professor at @UniFAU Erlangen-Nürnberg) and supported by the European Research Council (@ERC_Research), by the Swiss National Science Foundation @snsf_ch @NCCR_QSIT and by @ETH Zürich. The work was performed at the Department of Physics (@ETH_physics) of ETH Zurich.

Check out our new @qudev lab (@ETH_physics @ETHQuantumCntr) paper on entangling #quantum error corrected logical qubits in superconducting circuits entitled "Realizing Lattice Surgery on Two Distance-Three Repetition Codes with Superconducting Qubits" out on @arxiv today (. The work was done in collaboration with @fz_juelich and @RWTH Aachen, and was executed at the @ETH_en Zurich - @psich_en Quantum Computing Hub. The work was supported by @IARPAnews, by @SBFI_CH, by @Innosuisse, by the @ETHFoundation1 and by @ETH #Zurich.
