Lattice Surgery Achieved on Superconducting Repetition Codes

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: https://t.co/0psafX9XFl The paper is also available on @arxiv as https://t.co/qU55mWY6q5 . 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.
