    "abstract": "An experiment performed in 2002 by Sciarrino et al. provided a simple proof\nof the nonlocality of a single photon whose wave function is multi-branched.\nThe difference between this experiment and others similar, is that the\ntester-particle used by Sciarrino to \"feel\" this nonlocality is another photon\nidentical to the tested one. Such an experiment be can in principle performed\nwith fermions too, and this is the case ivestigated in this article. The novel\nphenomenon revealed by Sciarrino\u0027s experiment, is the particle \"borrowing\". If\na single particle is described by a two-branched wave function, then only one\nof these branches produces a detection at a time, the other ranch remains\n\"silent\". What happens in this experiment is that the silent branch \"borrows\" a\nparticle from another source, if available in the neighborhood, and also\nproduces a detection. To illustrate this feature more obviously, a modificaton\nof Sciarrino\u0027s experiment is proposed. Two sources of particles are made\navailable in the neighborhood of the two branches. What then happens is that\neach branch takes and populates itself with a particle from whichever source is\nat hand.",
