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…
Detecting Entanglement by Pure Bosonic Extension
Xuanran Zhu, Chao Zhang, Chenfeng Cao +3
In the realm of quantum information theory, the detection and quantification of quantum entanglement stand as paramount tasks. The relative entropy of entanglement (REE) serves as…
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…
On the mixed-unitary rank of quantum channels
Mark Girard, Debbie Leung, Jeremy Levick +4
In the theory of quantum information, the mixed-unitary quantum channels, for any positive integer dimension , are those linear maps that can be expressed as a convex combinatio…
Higher Rank Matricial Ranges and Hybrid Quantum Error Correction
David W. Kribs, Ningping Cao, Chi-Kwong Li +3
We introduce and initiate the study of a family of higher rank matricial ranges, taking motivation from hybrid classical and quantum error correction coding theory and its operator…
