A Three-Point Continuous-Variable Quantum MacWilliams Identity
Yinzi Xiao
The paper introduces a three-point continuous-variable quantum MacWilliams identity, provides its closed-form integral kernel, and uses it to derive semidefinite-programming bounds…

Symplectic Lattices and GKP Codes -- Simple Randomized Constructions from Cryptographic Lattices
Johannes Blömer, Yinzi Xiao, Zahra Raissi +1
We construct good GKP (Gottesman-Kitaev-Preskill) codes (in the sense of Conrad, Eisert and Seifert proposed) from standard short integer solution lattices (SIS) as well as from ri…

Sequential decoding of the XYZ hexagonal stabilizer code
Basudha Srivastava, Yinzi Xiao, Anton Frisk Kockum +2
Quantum error correction requires accurate and efficient decoding to optimally suppress errors in the encoded information. For concatenated codes, where one code is embedded within…
