About this paper
Dor Elimelech, Victor V. Albert, Alexander Barg
The authors define an approximate quantum error-correction framework for controlled channel families from error sets. Each channel’s Kraus operators are linear combinations of those errors, with coefficient matrix spectral norm at most one. Its erasure/general-error relation has dimension-dependent factors. For a two-mode GNU code, it bounds three-loss error by 0.006552 at photon number 9,216; recovery may depend on the channel.
