Abstract:
The teleportation of an unknown polarization state of one of the photons in a system of identical particles has
been considered. It has been shown that the spatial degrees of freedom, which are various directions of the
momentum of three photons, are of significant importance for teleportation in the system of identical
particles. The inclusion of the spatial degrees of freedom increases the dimension of the space of single-particle
states. In view of this increase, a four-dimensional subspace of two-particle states, which is similar to the
space of states spanned on the Bell states in the system of two distinguishable qubits, can be separated in the
experimental configuration.
