Subsystem CSS codes, a tighter stabilizer-to-CSS mapping, and Goursat's Lemma
Michael Liaofan Liu, Nathanan Tantivasadakarn, Victor V. Albert
The CSS code construction is a powerful framework used to express features of a quantum code in terms of a pair of underlying classical codes. Its subsystem extension allows for si…
