要旨:
In this contribution, we propose linear optical realizations of arbitrary stabilizer quantum error correction (QEC) codes in any dimension, including discrete and continuous quantum variables. Our protocols use graph states to encode arbitrary logical states in a systematic way. In this fashion, the hardest part of the encoding procedure (i.e., the generation of multi-party correlations robust against local errors) is shifted offline into the preparation of the graph-state ancilla.
