Hierarchical Quantum Error Correction with Hypergraph Product Code and Rotated Surface Code
Junichi Haruna, Keisuke Fujii
We propose and analyze a hierarchical quantum error correction (QEC) scheme that concatenates hypergraph product (HGP) codes with rotated surface codes and that is compatible with…

Logical entanglement distribution between distant 2D array qubits
Yuya Maeda, Yasunari Suzuki, Toshiki Kobayashi +3
Sharing logical entangled pairs between distant quantum nodes is a key process to achieve fault tolerant quantum computation and communication. However, there is a gap between curr…
