Bosonic quantum error correction using squeezed Fock states

Published 30 May 2025 in quant-ph | (2506.00300v1)

Abstract: In the paper, we develop a bosonic quantum error correction code based on squeezed Fock states. We compare our proposed code with one based on squeezed Schrodinger's cat states using the Knill-Laflamme cost function and the Petz map fidelity. We demonstrate that squeezed Fock states are competitive in protecting information in a channel with particle loss and dephasing.
