Long-range nonstabilizerness and quantum codes, phases, and complexity
Fuchuan Wei, Zi-Wen Liu
As a necessary resource for quantum computational advantage, quantum magic (nonstabilizerness) is of fundamental importance in the study of quantum computation and physics. We deve…

Theory of low-weight quantum codes
Fuchuan Wei, Zhengyi Han, Austin Yubo He +2
Low check weight is practically crucial code property for fault-tolerant quantum computing, which underlies the strong interest in quantum low-density parity-check (qLDPC) codes. H…

Noise robustness and threshold of many-body quantum magic
Fuchuan Wei, Zi-Wen Liu
Understanding quantum magic (i.e., nonstabilizerness) in many-body quantum systems is challenging but essential to the study of quantum computation and many-body physics. We invest…
