Learning to Decode Concatenated Quantum Codes with Hierarchical Message Passing
Jiahui Wu, Chao Zhang, Zipeng Wu +1
We introduce a neural message-passing framework for decoding general concatenated stabilizer codes. Soft beliefs propagate bidirectionally across concatenation levels, and lightwei…
Ising Dirac fermions across a topological phase transition
Aoqian Zhang, Yaqi Ma, Yifei Jin +14
Dirac fermions have attracted significant interest due to their relativistic dispersions and close connections to topological physics, yet they are generally expected to be gapped…
Bidirectional Decoding for Concatenated Quantum Hamming Codes
Chao Zhang, Zipeng Wu, Jiahui Wu +1
High-rate concatenated quantum codes offer a promising pathway toward fault-tolerant quantum computation, yet designing efficient decoders that fully exploit their error-correction…
Transversal Gates in Nonadditive Quantum Codes
Chao Zhang, Zipeng Wu, Shilin Huang +1
Transversal gates play a crucial role in suppressing error propagation in fault-tolerant quantum computation, yet they are intrinsically constrained: any nontrivial code encoding a…
Investigating Pure State Uniqueness in Tomography via Optimization
Jiahui Wu, Zheng An, Chao Zhang +3
Quantum state tomography (QST) is crucial for understanding and characterizing quantum systems through measurement data. Traditional QST methods face scalability challenges, requir…
