Error Correction of Beamsplitter-Generated Entangled GKP States
Moritz Fontboté-Schmidt, Jeremy Metzner, Florence Berterottière +8
To be useful, quantum computers will be required to successfully correct errors occurring at the hardware level. Bosonic codes provide a hardware-efficient option for error correct…

Tweezer-assisted subwavelength positioning of atomic arrays in an optical cavity
Matthias Seubert, Lukas Hartung, Stephan Welte +2
We present an experimental technique that enables the preparation of defect-free arrays of 87Rb atoms within a microscopic high-finesse optical standing-wave cavity. By employing o…

Two-qubit operations for finite-energy Gottesman-Kitaev-Preskill encodings
Ivan Rojkov, Paul Moser Röggla, Martin Wagener +4
We present techniques for performing two-qubit gates on Gottesman-Kitaev-Preskill (GKP) codes with finite energy, and find that operations designed for ideal infinite-energy codes…
