Optimal control with flag qubits
Liang-Xu Xie, Lui Zuccherelli de Paula, Weizhou Cai +6
High-fidelity quantum operations are the cornerstone of fault-tolerant quantum computation. In open quantum systems, traditional optimal control only passively resists decoherence,…

Fault-tolerant preparation of arbitrary logical states in the cat code
Zi-Jie Chen, Weizhou Cai, Liang-Xu Xie +5
Preparing high-fidelity logical states is a central challenge in fault-tolerant quantum computing, yet existing approaches struggle to balance control complexity against resource o…
