Global Precision Limits in Critical Quantum Metrology: From Cramér-Rao to Ziv-Zakai
Neng Zeng, Tao Liu, Yu-Ran Zhang
Critical quantum metrology with equilibrium states predicts quantum-enhanced sensitivity only in the vicinity of criticality, where large prior information about the parameter is r…
Nonlinear cascaded quantum network with giant emitters
Xin Wang, Jia-Qi Li, Zhihai Wang +4
Chiral quantum optics is central to developing scalable quantum networks, yet existing approaches rely predominantly on linear single-photon regimes. It remains unclear how to gene…
Chiral-Extended Photon-Emitter Dressed States in Non-Hermitian Topological Baths
Zhao-Fan Cai, Xin Wang, Zi-Xuan Liang +2
The interplay of quantum emitters and non-Hermitian structured baths has received increasing attention in recent years. Here, we predict unconventional quantum optical behaviors of…
Non-Hermitian sensing from the perspective of post-selected measurements
Neng Zeng, Tao Liu, Keyu Xia +2
By employing the Naimark dilation, we establish a fundamental connection between non-Hermitian quantum sensing and post-selected measurements. The sensitivity of non-Hermitian quan…
Long-Range Four-body Interactions in Structured Nonlinear Photonic Waveguides
Xin Wang, Jia-Qi Li, Tao Liu +2
Multi-photon dynamics beyond linear optical materials are of significant fundamental and technological importance in quantum information processing. However, it remains largely une…
