Entanglement-assisted quantum error correcting codes (EAQECCs) are a simple and
fundamental class of codes. They allow for the construction of quantum codes from classical …

One central theme in quantum error-correction is to construct quantum codes that have a
large minimum distance. Quantum maximal distance separable (MDS) codes are optimal in …

Quantum maximum-distance-separable (MDS) codes form an important class of quantum
codes. To get q-ary quantum MDS codes, one of the effective ways is to find linear MDS …

Let q be an odd prime power. Based on classical negacyclic codes, we construct two
classes of quantum maximum-distance-separable (MDS) codes with parameters [[q 2+ 1, q 2 …

The intersection () of a linear code and its Euclidean dual (Hermitian dual) is called the
Euclidean (Hermitian) hull of this code. It is natural to consider the hull-variation problem …

New stabilizer codes with parameters better than the ones available in the literature are
provided in this work, in particular quantum codes with parameters 127, 63, ≥ 12 _2 127 …

It has been a great challenge to construct new quantum maximum-distance-separable
(MDS) codes. In particular, it is very hard to construct the quantum MDS codes with relatively …

The entanglement-assisted stabilizer formalism provides a useful framework for constructing
quantum error-correcting codes (QECC), which can transform arbitrary classical linear codes …

Entanglement-assisted quantum error-correcting (EAQEC, for short) codes use pre-existing
entanglements between the sender and receiver to boost the rate of transmission. It is …

We present new bounds on the existence of general quantum maximum distance separable
codes (QMDS): the length $ n $ of all QMDS codes with local dimension $ D $ and distance …
