Heralded Non-Gaussian Squeezed-State Inputs for Parity-Detection SU(1,1) Interferometry
Lifen Guo, Qingqian Kang, Teng Zhao +3
Non-Gaussian operations can reshape the photon statistics of continuous-variable probes, but their metrological advantage is meaningful only when heralding probability and photon-n…
Fully-connected three-mode squeezed vacuum: Gaussian entanglement, steering, and collective photon subtraction
Manjia Mai, Jifeng Sun, Teng Zhao +2
We investigate a fully-connected three-mode squeezed vacuum (FC-C3MSV) state, where all three modes are pairwise coupled through nonlinear interactions in a triangle () topolo…
Enhancing Phase Estimation in a Hybrid Interferometer via Kerr Nonlinearity and Photon Subtraction
Lifen Guo, Qingqian Kang, Zekun Zhao +5
We propose a high-precision phase estimation scheme in a hybrid interferometer by synergistically combining a Kerr nonlinear phase shifter and multi-photon subtraction operations.…
Quantum Steering and Entanglement in a Tritter: Hierarchy under Loss
Jifeng Sun, Shumin Yang, Teng Zhao +2
We present a comprehensive phase diagram of quantum correlations in a three-mode Gaussian state generated by a tritter, driven by a two-mode squeezed vacuum and a coherent state. T…
Phase estimation via number-conserving operation inside the SU(1,1) interferometer
