Abstract
We introduce common eigenstates of many-particle compatible observables in n-mode Fock space. These states make a complete and orthogonal set and can be realized by the use of beam splitter devices. The entanglement properties of these states are exhibited, their applications in solving many-body problems and in quantum communication are shown.
