Approximate maximum-likelihood decoding via truncated free energies
Yuanqi Liu, Weilei Zeng, Junjie Wu +1
Maximum-likelihood decoding (MLD) achieves the minimum logical error rate of stabilizer codes under known i.i.d. Pauli noise, but its exact evaluation is \#P-hard. Practical pipeli…
An iterative Ising decoder for quantum error correction codes
Yuanqi Liu, Weilei Zeng, Peixiang Li +6
The Ising framework maps the decoding problem in quantum error correction onto ground-state optimization of a classical Hamiltonian, in which - error correlations enter as cr…
Quantum convolutional data-syndrome codes
Weilei Zeng, Alexei Ashikhmin, Michael Woolls +1
We consider performance of a simple quantum convolutional code in a fault-tolerant regime using several syndrome measurement/decoding strategies and three different error models, i…
Higher-dimensional quantum hypergraph-product codes
Weilei Zeng, Leonid P. Pryadko
We describe a family of quantum error-correcting codes which generalize both the quantum hypergraph-product (QHP) codes by Tillich and Zémor, and all families of toric codes on …
