Refined Belief-Propagation Decoding of Quantum Codes with Scalar Messages
Kao-Yueh Kuo, Ching-Yi Lai
Codes based on sparse matrices have good performance and can be efficiently decoded by belief-propagation (BP). Decoding binary stabilizer codes needs a quaternary BP for (additive…
Decoding of Quantum Data-Syndrome Codes via Belief Propagation
Kao-Yueh Kuo, I-Chun Chern, Ching-Yi Lai
Quantum error correction is necessary to protect logical quantum states and operations. However, no meaningful data protection can be made when the syndrome extraction is erroneous…
Constant depth fault-tolerant Clifford circuits for multi-qubit large block codes
Yi-Cong Zheng, Ching-Yi Lai, Todd A. Brun +1
Fault-tolerant quantum computation (FTQC) schemes using large block codes that encode qubits in physical qubits can potentially reduce the resource overhead to a great ex…
Carrying an arbitrarily large amount of information using a single quantum particle
Li-Yi Hsu, Ching-Yi Lai, You-Chia Chang +2
Theoretically speaking, a photon can travel arbitrarily long before it enters into a detector, resulting a click. How much information can a photon carry? We study a bipartite asym…
Refined Belief Propagation Decoding of Sparse-Graph Quantum Codes
Kao-Yueh Kuo, Ching-Yi Lai
Quantum stabilizer codes constructed from sparse matrices have good performance and can be efficiently decoded by belief propagation (BP). A conventional BP decoding algorithm trea…
Quantum Data-Syndrome Codes
Alexei Ashikhmin, Ching-Yi Lai, Todd A. Brun
Performing active quantum error correction to protect fragile quantum states highly depends on the correctness of error information--error syndromes. To obtain reliable error syndr…
