  The simple algorithm for the simulation and visualization of non relativistic
quantum dynamics is proposed that is based on a collective behavior of
classical particles. Any quantum particle is represented as the swarm of its
classical samples which interact by simple rules including emission and
absorption of samples of tied photons. The quantum dynamics results from the
collective behavior of such a swarm where the eigenstates are treated as the
equilibrium states relatively to emission-absorption of photons. The
entanglement is treated as a correlation between samples of the different
swarms that is stored in the space-time part of the model inaccessible for a
user. The amplitude is always grained. The Coulomb field between quantum
particles is simulated, analogously to free flow of quantum package, by the
point wise interaction between its samples and scalar photon samples which
propagate by diffusion. It gives square root speedup in comparison to
each-with-each method. This method obviously includes decoherence and admits
the natural generalization on the QED of many particles with the linear
computational cost.
