Abstract

A model of entangled quantum states of many bodies using tuples consisting of samples of individual real particles is proposed. This approach generalizes Bohm’s method for complex systems. The dynamics can be described both in the form of quantum hydrodynamics and in the form of dynamic diffusion which is examined in detail in this study. The latter method fundamentally differs from the choice of the grain of spatial resolution and cannot be reduced to differential equations; therefore, it requires direct simulation. The limitation on the number of samples is the fundamental factor causing decoherence, a deviation of the swarm dynamics from the exact solution to the Schrödinger equation. The model complexity is linear with respect to the number of particles.
