Lensing and enhanced single atom detection via a single-pixel nanostructure
Ling-Xiao Wang, Lei Xu, Ai-Ping Liu +7
We propose and demonstrate a general mechanism for nanoscale lensing based on the phase gradient imposed by a single nanostructure scattering light in its near-field. We verify thi…
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,…
Robust and optimal control of open quantum systems
Zi-Jie Chen, Hongwei Huang, Lida Sun +9
Recent advancements in quantum technologies have highlighted the importance of mitigating system imperfections, including parameter uncertainties and decoherence effects, to improv…
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…
Deterministic Generation of Arbitrary Fock States via Resonant Subspace Engineering
Shan Jin, Ming Li, Weizhou Cai +10
Deterministic preparation of high-excitation Fock states is a central challenge in bosonic quantum information, with control complexity that generically explodes as the Hilbert spa…
Efficient implementation of arbitrary Hermitian-preserving and trace-preserving maps
Weizhou Cai, Zi-Jie Chen, Xuanqiang Zhao +4
Quantum control has been a cornerstone of quantum information science, driving major advances in quantum computing, quantum communication, and quantum sensing. Over the years, it h…
