摘要

Our primary purpose of this work is to explicitly construct the general multipartite Einstein Podolsky-Rosen (EPR) entangled state in multi-mode Foek space for a system with different masses of particles,which makes up a new quantum mechanical representation owing to completeness relation and orthogonal property.Its entanglement can be seen more clearly by analyzing its standard Sehmidt decomposition.In addition,some applications of the multipartite entanglement are proposed including deriving the generalized Wigner operator and squeezing operator.
