Bosonic quantum error correction using squeezed Fock states
arXiv:2506.00300 · doi:10.1103/97yt-nzg2
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.
