Entangled solitons and quantum mechanics

Special stochastic realization of the wave function in quantum mechanics (QM), with the inclusion of soliton representation of extended particles within the scope of nonlinear spinor field model, is considered. Two-solitons configurations are used for constructing entangled states in generalized QM dealing with extended 1/2-spin particles. Entangled solitons construction is used for calculating the Einstein - Podolsky - Rosen (EPR) spin correlation, which is shown to coincide with the quantum mechanical one for the two 1/2-spin particles in the singlet state. © 2007 American Institute of Physics.
