To study the properties of the probabilistic bits the geometric approach is preferable. In this approach
the projective interpretation of the Hilbert space as the space of rays is used. This model can be employed
for simulating Bi-photons, qubits, EPR states and entanglement. The other example concerns the entangled
envelope solitons in Kerr dielectric with cubic nonlinearity, where we use two-solitons configurations for
modeling the entangled states of photons.
We consider optical 1D envelope solitons in Kerr dielectric with cubic nonlinearity and use two-solitons configurations
for modelling entangled states of photons. We calculate spin, momentum and energy of solitons on the
basis of approximate solutions to the nonlinear Maxwell equations and construct entangled two-solitons singlet
states in special stochastic representation.
