Spatio-temporal Path Optimization for Stabilizer-Code-Protected Quantum Networks
Yuanbo Zhang, Qianfan Wang, Yangming Zhao +2
Quantum Error Correction~(QEC)-protected direct transmission is a fundamental approach to preserve fragile quantum states while they are physically forwarded across noisy quantum n…
Optimal qudit overlapping tomography and optimal measurement order
Shuowei Ma, Qianfan Wang, Lvzhou Li +1
Quantum state tomography is essential for characterizing quantum systems, but it becomes infeasible for large systems due to exponential resource scaling. Overlapping tomography ad…
Guessing Decoding of Short Blocklength Codes
Qianfan Wang, Jifan Liang, Peihong Yuan +3
Future beyond-5G and 6G systems demand ultra-reliable, low-latency communication with short blocklengths, motivating the development of universal decoding algorithms. Guessing deco…
A High-Performance List Decoding Algorithm for Surface Codes with Erroneous Syndrome
Jifan Liang, Qianfan Wang, Lvzhou Li +1
Quantum error-correcting codes (QECCs) are necessary for fault-tolerant quantum computation. Surface codes are a class of topological QECCs that have attracted significant attentio…
Random Staircase Generator Matrix Codes: Performance Analysis and Construction
Qianfan Wang, Yiwen Wang, Yixin Wang +2
In this paper, we propose a class of codes, referred to as random staircase generator matrix codes (SGMCs), which have staircase-like generator matrices. In the infinite-length reg…
