Bosonic quantum error-correcting codes with finite stellar rank
Rui Wang, Adithi Udupa, Timo Hillmann +3
Bosonic quantum error correction (QEC) relies on non-Gaussian bosonic encodings whose preparation cost is a central practical constraint. In this work, we use stellar rank as a res…
Surface code logical operations on a superconducting quantum processor
Weiping Lin, Shaojun Guo, Yuwei Ma +144
Fault-tolerant quantum computation requires logical operations that manipulate encoded information while preserving quantum error-correction protection. In planar surface-code arch…
Bias-Preserving Gates and Quantum Error Correction With Dual-Rail Cat Codes
Debjyoti Biswas, Nikhil Sharma, Alberto Salvador +4
Scalable fault-tolerant quantum computation requires quantum error-correcting codes that simultaneously support universal logical operations, suppress hardware-specific noise, and…
Generation of 95-qubit genuine entanglement and verification of symmetry-protected topological phases
Tao Jiang, Jianbin Cai, Junxiang Huang +152
Symmetry-protected topological (SPT) phases are fundamental features of cluster states, serving as key resources for measurement-based quantum computation (MBQC). Generating large-…
