What Must a Quantum-Memory Decoder Know About Temporally Correlated Noise?
Danesh Morales-Hashemi, Graeme Smith, Ningping Cao
What must a quantum error-correction decoder know about temporally correlated noise, and what does it cost to learn? We study this question for fixed stabilizer memory experiments…
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…
Quantum Error Corrected Non-Markovian Metrology
Zachary Mann, Ningping Cao, Raymond Laflamme +1
Quantum metrology aims to maximize measurement precision on quantum systems, with a wide range of applications in quantum sensing. Achieving the Heisenberg limit (HL) - the fundame…
Quantum Maps Between CPTP and HPTP
Ningping Cao, Maxwell Fitzsimmons, Zachary Mann +2
For an open quantum system to evolve under CPTP maps, assumptions are made on the initial correlations between the system and the environment. Hermitian-preserving trace-preserving…
Maximum entropy methods for quantum state compatibility problems
Shi-Yao Hou, Zipeng Wu, Jinfeng Zeng +4
Inferring a quantum system from incomplete information is a common problem in many aspects of quantum information science and applications, where the principle of maximum entropy (…
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…
