Affine-Profile Stabilizer Thresholds for Magic in Codeword-Stabilized Quantum Codes
Li-Yi Hsu, En-Jui Kuo
Codeword-stabilized quantum codes give a unified graph-state description of stabilizer and nonadditive quantum error-correcting codes. Although each individual CWS word state is st…

Self-Testing Quantum Error Correcting Codes: Analyzing Computational Hardness
En-Jui Kuo, Li-Yi Hsu
We present a generalization of the tilted Bell inequality for quantum [[n,k,d]] error-correcting codes and explicitly utilize the simplest perfect code, the [[5,1,3]] code, the Ste…
