Tripartite Nonlinear Entangled State Representations in Quantum Mechanics
Fan Hong‐Yi, Chao Li
Abstract
Based on the technique of integral within an ordered product of nonlinear bosonic operators we construct a kind of tripartite nonlinear entangled states, which can make up a complete set. As its application, we also derive nonlinear 3-mode charge-related entangled state. The essential point for constructing these states lies in choosing the appropriate charge operator.
