The complexity of Gottesman-Kitaev-Preskill states

L Brenner, L Caha, X Coiteux-Roy, R Koenig - arxiv preprint arxiv …, 2024 - arxiv.org
We initiate the study of state complexity for continuous-variable quantum systems.
Concretely, we consider a setup with bosonic modes and auxiliary qubits, where available …

Engineering high-order nonlinearities while suppressing lower-order terms is crucial for
quantum error correction and state control in bosonic systems, yet it remains an outstanding …
