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…

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…
