Query: Random Shooting of Entangled Particles in Vacuum   The effect of random shooting of particles is considered on the basis of
solution of the Schrodinger equation and in terms of the Wigner function.
Two-particles description shows, in particular, that initial correlation leads
to high velocities of particles. This could be a potential mechanism for
obtaining energy. Evolution of the n-particle probability distribution is
descibed analytically.
