Jie Zhou, Chuanlong Ma, Yifang Xu +9
Entanglement is crucial for quantum networks and computation, yet maintaining high-fidelity entangled quantum states is hindered by decoherence and resource-intensive purification…
Quantum Confocal Microscopy in Fock Space with a 19 dB Metrological Gain
Ziyue Hua, Chuanlong Ma, Yilong Zhou +12
Quantum metrology promises measurement precision beyond classical limits by exploiting large-scale quantum states, yet realizing this advantage faces two fundamental challenges: th…
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…
Error-detectable Universal Control for High-Gain Bosonic Quantum Error Correction
Weizhou Cai, Zi-Jie Chen, Ming Li +5
Protecting quantum information through quantum error correction (QEC) is a cornerstone of future fault-tolerant quantum computation. However, current QEC-protected logical qubits h…
Echoed Random Quantum Metrology
Dong-Sheng Liu, Zi-Jie Chen, Ziyue Hua +8
Quantum metrology typically demands the preparation of exotic quantum probe states, such as entangled or squeezed states, to surpass classical limits. However, the need for careful…
Principles of Optics in the Fock Space: Scalable Manipulation of Giant Quantum States
Yifang Xu, Yilong Zhou, Ziyue Hua +11
