Geometry of Knill-Laflamme Coefficients for Pauli Error Detection

Baisong Sun, Ningping Cao, Yiu Tung Poon +1

Knill-Laflamme coefficients characterize exact quantum error detection through scalar compressions of error operators to the code space. For prescribed Pauli observables and a fixe…

Characterizing Quantum Codes via the Coefficients in Knill-Laflamme Conditions

Mengxin Du, Chao Zhang, Yiu-Tung Poon +1

Quantum error correction (QEC) is essential for protecting quantum information against noise, yet understanding the structure of the Knill-Laflamme (KL) coefficients from…

NISQ: Error Correction, Mitigation, and Noise Simulation

Ningping Cao, Junan Lin, David Kribs +3

Error-correcting codes were invented to correct errors on noisy communication channels. Quantum error correction (QEC), however, may have a wider range of uses, including informati…
