Heptagon holographic code[1]
Also known as Holographic Steane code.
Description
Holographic tensor-network code constructed out of a network of encoding isometries of the Steane code. Depending on how the isometry tensors are contracted, there is a zero-rate and a finite-rate code family.
Decoding
Optimal erasure decoder [1].
Code Capacity Threshold
\(~33\%\) under erasures using optimal erasure decoder for the finite-rate family, and \(50\%\) for the zero-rate family [1].Depolarizing noise: \(9.4\%\) using tensor-network decoder, and \(\approx 7\%\) using integer optimization decoder [2].\(18.985\%\) against depolarizing noise for zero-rate code under tensor-network decoder [3].
