A graph-based approach to entanglement entropy of quantum error correcting codes
Wuxu Zhao, Menglong Fang, Daiqin Su
We develop a graph-based method to study the entanglement entropy of Calderbank-Shor-Steane quantum codes. This method offers a straightforward interpretation for the entanglement…

Quantum memory based on concatenating surface codes and quantum Hamming codes
Menglong Fang, Daiqin Su
Designing quantum error correcting codes that promise a high error threshold, low resource overhead and efficient decoding algorithms is crucial to achieve large-scale fault-tolera…
