Generalized Conditional Displacement
arXiv:2405.09977 · doi:10.22331/q-2025-12-10-1934
Abstract
Conditional displacement with a qubit ancilla is a critical component in continuous-variable error correction protocols. We present the generalized conditional displacement operator, conditioned on a qudit ancilla, and explore potential implementations. We show how this operator can be used to enhance error correction with Gottesman-Kitaev-Preskill (GKP) codes.
