Decoherence in simple experiments with Bose-Einstein condensates is of great importance for quantum engineering. We study a system of two colliding condensates in Fock and correlated states. During the collision some atoms are scattered out of the condensates, which leads to the decoherence. The quantum dynamics of the condensates is described by a master equation. In a simplified model we present analytical results. For more realistic conditions numerics is invoked. The depletion of the colliding condensates is accompanied by a decoherence.
