Taking this one step further, we consider a model of computation that disregards even the topology of the particle trajectory, and computes by permuting particles.

First, we show that a perturbation of order O(1/N) is sufficient and, in general, necessary to destroy the entanglement of any state admitting an N Bose symmetric extension.
