Three dimensional (3D) toric codes are a class of stabilizer codes with local checks and come under the umbrella of topological codes. While decoding algorithms have been proposed for the 3D toric code on a cubic lattice, there have been very few studies on the decoding of 3D toric codes over arbitrary lattices. Color codes in 3D can be mapped to toric codes. However, the resulting toric codes are not defined on cubic lattice. They are arbitrary lattices with triangular faces. Decoding toric… 

Decoding Pauli-Z Errors on the 3-Dimensional Tetrahedral Color Code with Boundaries

The tetrahedral color code can be utilized for measurement-based quantum computing, for which all entanglement is present in a cluster state at the beginning of the computation and gate operations are performed by local measurements and classical operations.

Cellular automaton decoders for topological quantum codes with noisy measurements and beyond

An error correction procedure based on a cellular automaton, the sweep rule, is proposed, which is applicable to a broad range of codes beyond topological quantum codes and is also essentially insensitive to the details of the lattice and noise model.

Numerical Implementation of Just-In-Time Decoding in Novel Lattice Slices Through the Three-Dimensional Surface Code.

A fully detailed set of bounded-height lattice slices through the 3D codes which retain the code distance and measurement-error detecting properties of the full 3D code and admit a dimension-jumping process which expands from/collapses to 2D surface codes supported on the boundaries of each slice.

Single-Shot Error Correction of Three-Dimensional Homological Product Codes

It is proved that all three-dimensional homological product codes exhibit confinement in their $X$-components and are therefore single-shot for adversarial phase-flip noise, and confinement is sufficient for single- shot decoding of adversarial errors.

A Decoder for the Color Code with Boundaries

A decoder for the 3D color code with boundaries is introduced, which is a variation of the restriction decoder introduced by Kubicka and Delfosse, and the lift procedure is adapted to efficiently find a correction on qubits adjacent to a boundary.

It is shown that the color code on a d-dimensional closed manifold is equivalent to multiple decoupled copies of the d- dimensional toric code up to local unitary transformations and adding or removing ancilla qubits.

Cellular-Automaton Decoders with Provable Thresholds for Topological Codes.

A new cellular automaton (CA), the sweep rule, is proposed, which generalizes Toom's rule to any locally Euclidean lattice and leads to new CA decoders with provable error-correction thresholds for other topological quantum codes including the color code.

This work designs a fast decoding algorithm for topological codes to correct for Pauli errors and erasure and combination of both errors and Erasure and has a worst case complexity of O(nα(n), where n is the number of physical qubits and α is the inverse of Ackermann's function, which is very slowly growing.
