QIP 2023 Poster Abstract: A fast renormalization-group tensor-network decoder for quantum low-density parity check codes.

2022

We present a fast and Bayes-optimal-approximating tensor network decoder for quantum LDPC codes based on the tensor-entanglement renormalization group algorithm, originally proposed by Gu, Levin, and Wen.By precomputing the renormalization group flow for the null …
