Towards Scalable Bosonic Quantum Error Correction
Barbara M. Terhal, Jonathan Conrad, Christophe Vuillot
We review some of the recent efforts in devising and engineering bosonic qubits for superconducting devices, with emphasis on the Gottesman-Kitaev-Preskill (GKP) qubit. We present…

Code Deformation and Lattice Surgery Are Gauge Fixing
Christophe Vuillot, Lingling Lao, Ben Criger +3
The large-scale execution of quantum algorithms requires basic quantum operations to be implemented fault-tolerantly. The most popular technique for accomplishing this, using the d…

Quantum Error Correction with the Toric-GKP Code
Christophe Vuillot, Hamed Asasi, Yang Wang +2
We examine the performance of the single-mode GKP code and its concatenation with the toric code for a noise model of Gaussian shifts, or displacement errors. We show how one can o…
