Abstract

Based on Einstein, Podolsky and Rosen (EPR) quantum entanglement, we construct a new kind of four-mode entangled states of continuous variables in Fock space and examine its complete property and partly non-orthonormal property. A set-up of one beamsplitter and two polarizers can generate such a four-mode entangled state. The discussion can also be extended to constructing more particles' entangled states.
