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…
Device-Independent Randomness Amplification
Anatoly Kulikov, Simon Storz, Josua D. Schär +6
Successful realization of Bell tests has settled an 80-year-long debate, proving the existence of correlations which cannot be explained by a local realistic model. Recent experime…
Two-photon cooling of calcium atoms
Wojciech Adamczyk, Silvan Koch, Claudia Politi +6
We demonstrate sub-Doppler cooling of calcium atoms using a two-photon transition from the ground state to the upper state via the intermediate s…
Complete Self-Testing of a System of Remote Superconducting Qubits
Simon Storz, Anatoly Kulikov, Josua D. Schär +6
Self-testing protocols enable the certification of quantum systems in a device-independent manner, i.e. without knowledge of the inner workings of the quantum devices under test. H…
