A Three-Point Continuous-Variable Quantum MacWilliams Identity
Yinzi Xiao
We construct the three-point continuous-variable (CV) quantum MacWilliams identity, extending the two-point framework of Burchards, and give its closed-form integral kernel. Its co…

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…
