A re-entrant chip-free-space photonic interface for telecom-to-Rubidium spectroscopy
Jia-Lin Chen, Ruixin Zhou, Deng-Hong Liu +13
The paper presents a re‑entrant chip‑free‑space interface where a thin‑film lithium niobate photonic circuit frequency‑doubles telecom light to 780 nm, sends it through a rubidium…
Magnetic-free optical mode degeneracy lifting in lithium niobate microring resonators
Xin-Biao Xu, Zheng-Xu Zhu, Yuan-Hao Yang +9
Breaking time-reversal symmetry in integrated photonics without magnetic fields remains a fundamental challenge. We demonstrate phonon-induced non-reciprocity through direct liftin…
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…
