On Propagation Rules for Entanglement-Assisted Quantum Codes
Gaojun Luo, Lin Sok, Martianus Frederic Ezerman, San Ling · 2023
This paper proposes new propagation rules on quantum codes in the entanglement-assisted scenario. The rules lead to new families of such quantum codes whose parameters are demonstrably optimal. To obtain the results, we devise tools to puncture and shorten codes in ways that ensure their Hermitian hulls have certain desirable properties.
