TLDR
Rate-(n-2)/n unrestricted and CSS-type quantum convolutional codes with up to 4096 states and minimum distances up to 10 are constructed as stabilizer codes from classical self-orthogonal rate-1/n F4-linear and binary linear convolutionAL codes, respectively.
Abstract
Rate-(n-2)/n unrestricted and CSS-type quantum convolutional codes with up to 4096 states and minimum distances up to 10 are constructed as stabilizer codes from classical self-orthogonal rate-1/n F4-linear and binary linear convolutional codes, respectively. These codes generally have higher rate and less decoding complexity than comparable quantum block codes or previous quantum convolutional codes. Rate-(n-2)/n block stabilizer codes with the same rate and error-correction capability and essentially the same decoding complexity are derived from these convolutional codes via tail-biting

On the iterative decoding of sparse quantum codes

TL;DR: These results indicate that the main source of errors in the quantum coding scheme remains in the decoding, and propose heuristic methods to improve belief propagation decoding specifically targeted at these two problems.

Catalytic quantum error correction

TL;DR: The theory of entanglement-assisted quantum error-correcting (EAQEC) codes is developed, a generalization of the stabilizer formalism to the setting in which the sender and receiver have access to presharedEntanglement, which greatly simplifies their construction.

Entanglement-assisted quantum turbo codes

TL;DR: It is proved that entanglement is the resource that enables a convolutional encoder to be both non-catastrophic and recursive because an encoder acting on only information qu bits, classical bits, gauge qubits, and ancilla qubits cannot simultaneously satisfy them.

Mixed State Entanglement and Quantum Error Correction

TL;DR: It is proved that an EPP involving one-way classical communication and acting on mixed state M (obtained by sharing halves of Einstein-Podolsky-Rosen pairs through a channel) yields a QECC on \ensuremath{\chi} with rate Q=D, and vice versa, and it is proved Q is not increased by adding one- way classical communication.
