Good Gottesman-Kitaev-Preskill codes from the NTRU cryptosystem

J Conrad, J Eisert, JP Seifert - Quantum, 2024 - quantum-journal.org
We introduce a new class of random Gottesman-Kitaev-Preskill (GKP) codes derived from
the cryptanalysis of the so-called NTRU cryptosystem. The derived codes are $ good $ in …
